WITH regards to your story about the increase in the number of collisions on 20mph roads.

So by decreasing the number of 30mph roads while simultaneously increasing the number of 20mph roads, we see 20mph casualties rise?

What kind of magic is this?

The IAM has been very strategic with this report and has taken advantage of both the lack of real statistics around the 20mph implementations and also of the fact that the 20mph limit is simply not enforced in the same way that 30mph limits are. Ask anyone who lives on a 20mph road if people obey the limit and they will tell you a resounding ‘no’.

If I ever drive along a 20mph road (doing 20mph) I can guarantee within seconds I’ll have an angry looking individual up behind me getting frustrated.

The question the IAM and ourselves should be asking is, out of the incidents that happen at 20mph and those that happen at 30mph, which ones produce the most casualities? If people actually obeyed the speed limit, would 20mph or 30mph be safer? You don’t need to be a genius to work out the answer.
