@TDCN @acs 5 out of 5 pedestrians will survive a collision with a car traveling at 20km/hr, only 4 out of 5 will survive a collision with a car traveling at 40km/h.
This doesn't include the large difference in level of injury.
So by speeding your taking a situation where nobody should die and making it a situation where someone might.
A 20km/h area is an area where there will be lots of people to hit so it's even more important to stick to the speed limit in that situation
@nicklockwood @TDCN @Showroom7561 you're right. Mandatory speed limiters are a much better option. They're cheap, easy and avoid having to fine people.
