The two ton vehicle slamming into a pedestrian at medium speeds will probably kill them.
The only way to solve this problem is to lower speeds or remove the car from the road.
A typical European car hitting a pedestrian at 30mph is 80% survivable.
(This road safety video is 14 years old now, and since then some places in the UK have managed to introduce 20mph limits, which are even better.)
