Unlike the NHTSA tests, the Euro NCAP tests include tests of pedestrian, cyclist and motorcyclist protection - both passive protection to mitigate injury in the event of a collision, and active protection to prevent a collision in the first place. Performance in these tests count towards the overall 5 star rating. My understanding is that NHTSA is working on preliminary research into the issue, but they're a clear 15-20 years behind Euro NCAP.

A lack of visibility regulation is the biggest problem in current vehicle design in my opinion. A 5' (152 cm) tall driver should be able to clearly see a small child standing a few feet away in front of or to either side of any vehicle allowed on public streets. Any vehicle modification compromising that should be strictly prohibited.

Steep financial liability for pedestrian/cyclist accidents for not only the driver but also the vehicle manufacturer or anyone involved in modifying a vehicle would also help.

Right. Regulation is what works, but it's not a magic wand. We can't keep allowing industries to write their own regulations without meaningful public input.
