Worth noting that there is a huge difference between being hit at 20 or 40 mph. This study showed risk of severe injury of 25% at 23mph vs 75% at 39mph and risk of death of 10% at 23mph and 50% at 42mph. There is also the impact zone/characteristics, F150 with the tall & flat front will be much more dangerous in an impact than if it had a shorter height and was sloped which could roll someone over the hood. And other considerations like trucks are heavier and have worse visibility. But I agree stopping speed isn’t the end all be all for road safety, but one factor of many that need to be taken into account.
