BMW's Z4 roadster (convertible) sports car employs technology that belongs in lots of cars, not just $50,000 two-seaters. The double-clutch transmission smoothly combines the power and performance of the manual gearbox it really is with the ease of an automatic (no clutch pedal). And the transflective LCD display is unaffected by sunlight. In fact, the more sun shines down, the brighter it gets. The iDrive controller finally works, and well. HD Radio is now free (some models) but the iPod adapter remains an overpriced option. It's a great car if your stock portfolio is fully recovered.
Another Practical Impractical BMWBMW's mainstream cars, particularly the 3 Series and 5 Series, do everything right: handling, safety, comfort, technology, status, residual value. They're practical cars for those with the means to afford them. The Z4 represents the other side of BMW, along with the BMW 6 Series and the BMW X6. They're what I consider impractical cars with a practical bent: Nobody needs them but when you buy one, you're delighted at how well they're suited to daily driving, unlike the the Pontiac Solstice with zero cockpit or trunk room, or the old Ferrari that only comes out on sunny weekends and needs $2,500 tune-ups.
Here's what delighted me with the BMW Z4 in the way of intelligent technology and smart design. The fact that BMW puts it into cars out of the reach of most buyers doesn't keep some or all of it trickling from down over time to more affordable brands and models. Much of this represents intelligent use of suppliers. Others could use them also.
Double-clutch transmission. It's a seven-speed manual gearbox with a clutch (two, actually) but electronics and hydraulics shift gears for you (no clutch pedal). It's quicker and more fuel-efficient than an automatic transmission and, at least for now, cooler to tell people about. Porsche invented the technology, Audi made the most use of it, and now BMW has a first-class version, unlike its clunky. Good news: At $1,525, it's only $200 more than a BMW automatic transmission and far less than the $2,900 BMW charges you for DCT when you buy a BMW M3 (more software in the M3 DCT, BMW says). Bad news: It's only available on the costlier twin-turbo Z4 sDrive35i; with the base model sDrive30i, you have to stick with the traditional automatic.

The National Highway Traffic Safety Administration estimates that 37,313 people were killed in motor vehicle traffic crashes in 2008. If that isn't a reason to become a better driver, then we don't know what is.
In an ideal world, drivers would execute every road maneuver with precision and ease. Sadly, we do not live in a never-never land, and not everyone walks away from metal-to-metal mayhem. Truth is that drivers are not created equal. Some are too brash, others too conservative. Some are even downright clueless. The common thread is that they can all turn a pleasant day on the motorway into a surreal nightmare in the blink of an eye.
To help you stay safe behind the wheel, here's a list of 10 driving behaviors to avoid.
Swerving
The No. 1 fatal mistake made by drivers is perhaps the most simple: not staying in their own lane — i.e., running off the road or drifting into the adjacent lane. According to the National Highway Traffic Safety Administration, in 2007, 15,574 people died in crashes where the driver simply couldn't stay in the lane.
Driving While Drowsy
"Driving a vehicle when you are fatigued is as dangerous as driving while impaired by alcohol or drugs," National Transportation Safety Board Acting Chairman Mark V. Rosenker said after a fatal highway accident in 2003 in which a college student who had been awake for the previous 18 hours was driving a carload of fellow students at 5 a.m. According to the NHTSA, in 2007 fatigued driving caused the deaths of 1,404 people, and more traffic fatalities occurred during the hours when most people are accustomed to being asleep (3 a.m. to 6 a.m.) than at any other time of day.
Drinking and Driving
Every 40 minutes someone dies in a drunk-driving accident. (In all 50 states, a blood-alcohol level of 0.08 percent or more is considered illegal, but a little-known fact is that you can be charged with driving while impaired even if you're under the legal limit.) Young drivers are particularly prone to drinking and driving: The 21- to 34-year-old set is responsible for well over half of alcohol-infused fatal crashes. Not surprisingly, the decision to get behind the wheel while intoxicated is made most often at night and on the weekends. According to the NHTSA, 60 percent of drivers who died after dark in 2007 were legally drunk. Alcohol is also a factor in half of pedestrian traffic deaths — both drivers and pedestrians are the culprits.
Overcorrecting
You get panicky when the wheels of your SUV hit the rumble patch on the shoulder of the highway, so you throw the steering wheel in the opposite direction to get the vehicle back on the road. This is a classic example of overcorrecting or oversteering, and it's a particularly perilous maneuver when you're behind the wheel of an SUV driving on the highway at high speeds. Consider it a rollover waiting to happen. More than 4 percent of automobile fatalities a year occur because of drivers overcorrecting.
Speeding
Racing, driving faster than the posted speed limit or simply going too fast for road conditions — i.e., speeding — comprises the second highest cause of death in fatal crashes, according to the NHTSA. Once you hit 55 mph, you're in the danger zone: 30 percent of fatalities occur at 55 or above. The worst-case scenarios invariably involve speeding without wearing a seat belt or a motorcycle helmet. Fatality rates for speeding motorcyclists are shockingly high: In 2007, speeding was a factor in 36 percent of motorcycle fatalities. Of those, 41 percent of drivers and more than half of passengers were not wearing helmets (only 20 states and the District of Columbia require helmets).
If you are comfortable driving faster than the speed limit then you should be comfortable with the fact that speeding was responsible for over 30 percent of the auto-related fatalities in the U.S. last year.
Failure to Yield Right of Way
For drivers age 70 and above, failing to yield while merging into traffic is the top cause of crashes. In a recent study by the Insurance Institute for Highway Safety, drivers 80 and older simply fail to see the other vehicle they should be yielding to. Drivers 70 to 79 see the vehicle but misjudge whether they have time to proceed ahead of it. Failure to yield right of way was the fifth leading cause of fatal crashes in 2007.
Erratic or Reckless Driving
At its mildest, we're talking about weaving and tailgating; at its most severe, this kind of driving involves steering down the wrong side of the road, exceeding the speed limit by 20 mph or doing more than 80 mph, and worse. Reckless driving can bring fines, jail time — and death. More than 1,850 fatalities in 2007 were the result of erratic or reckless drivers.
Running Red Lights
A whopping 75 percent of automobile crashes occur in cities, according to the nonprofit Insurance Research Council. The most common cause of these accidents? Hitting the gas when the light turns red. Of the myriad types of collisions that can result, head-on and side-impact collisions are the most dangerous. NHTSA statistics show that of the 41,059 automobile fatalities in 2007, 54 percent occurred in cars that sustained frontal damage. When you cut it too close while running a light, your front end or another car's front end is impacted. Either way, it's a recipe for a deadly accident.
Not Wearing a Seat Belt
Despite the fact that seat belt use is far more prevalent than even a decade ago — not to mention being legally required — 33 percent of people who die in vehicle fatalities failed to buckle up. Without a seat belt, car drivers and passengers put themselves at risk of being ejected from a vehicle, and 76 percent of the time the ejection ends in death.
