High waistlines (a style consideration) and thick roof pillars (from side airbags) happened.
But I think it's mostly just people being complete idiots the moment they step into a car.
Or we could just teach our children not to play in or around cars...
If cars had to be designed for every contingency it's moron owner would put it through, I would guess even a "cheap" car would be well into six figures, even excluding amortized R&D costs.
NHTSA: "You need a billion airbags in your pillars and need them to hold up 3x the weight of the vehicle!"
<pillars get thick and visibility reduced>
NHTSA: "Your visibility sucks, you now must have cameras!"
<everyone hates NHTSA>
Wish I could have added one to my new vehicle for $180 instead of having to pay $2k for the technology package.
My grandmother is 89 and drives a Trailblazer. She was at Target the other day and this woman with her brood of three were going into the store and walking behind her car.
She got in, watched them walk off, and noticed only two of the spawn were visible. She got out and the third was behind her car picking up something off the ground. No camera needed.
I do not need or want any of these so "help the idiot driver extras" such as:
Active Suspension .. wait till you get the bill when it fails. Way more than standard struts.
Rear View camera .. nice in some cases, like hooking up a trailer, but costs too much.
Tire Pressure Senors .. nice, but the sensors get replaced every 3rd or 4th set of tires at a fairly high cost. Also on some cars, you can not easily reset the sensor or the pressure at which it alerts at. Or what is the "normal psi" you would like to run. Not everyone runs the factory PSI (I go about 3 up)
Antilock brakes .. they have been out many years and are one item that actually does help.
no more shocking than mandating that cars have seatbelts.
Federally mandated electronic stability control requires that a lot of hi-tech stuff be added to every car, including those tire pressure sensors.
