In the news

I think I've (you've) found the nub of the issue here - we're not comparing eggs with eggs.

Dense city centre traffic =/= Faster roads with lighter traffic.

I appreciate hearing is of less importance in the latter but would still submit that voluntarily blocking out a sense in a life and death activity is not a sensible course of action.

Alternatively it might make everyone a better road user if they had headphones on and therefore had to check things visually before performing a manouver?
