People asked the same thing about the original DS before it came out regarding touch screen. Turned out just fine.
Same can be asked about playing a PSP with analog using presise movements,works just fine.
Unless you plan to go on dirt roads and 4 wheeling while game playing where your head is hitting the roof of the car then why worry?
Most the time in the car you will be on city streets with maybe an occasional speed bump or pothole.
This is nothing to worry about.
