Cars already have data logging black boxes, and, in the case of OnStar, can already send out a help message in a crash and record in-car audio. Connecting that with the in car GPS is only a software program away.

Sounds like it's nearly already here.

This tears my heart out every time I hear of it, but something that prevents parents from leaving their babies/children in the 140 degree car while they are at work, at the mall, etc. It could detect any source and prevent the car from being locked until EVERYONE is out of the car and you have to put a personal code in to lock the doors.

I have to go with 4-wheel-drive also, but there are far too many people who own one and have no idea how to use it. A lever on the floor or button on the dash labeled "4WD" isn't magic. Heck, I've even talked to people who thought their 2WD SUV was 4WD, they had no clue.

Booster lugs far enough away from the battery that people quit blowing them up when trying to boost start their cars.

Something to force childern to be in a proper seat for their age. This has turn into a grip for me and something I never noticed before. Countless times I see people driving with their kids not buckled in or babies on their laps. If you use your own seatbelt, shouldn't you use one for the most important person(s) in your life?

Sorry for going off topic...

Do you think they'll become a)required, and b) used for legal purposes, either post-collision or traffic law enforcement?

We half-jokingly say we need a law that allows ambulances to make traffic stops for this one purpose. It doesn't take too many dead babies before you develop some pretty strong feelings about it.

Don't some European countries require FEs already? (Germany?)

Oddly, I've seen plenty of car fires, but darn few as a result of a collision.

Not too odd- none of the car fires I've seen were from collisions either. And, yeah, I'd have loved to pull over some folks. Still want to.
