Frankly, I don't care if the speed limit is 30 MPH. If everyone is going 40 MPH, it is safer to go 40 MPH like everyone else. If you're so dead set though going 30 MPH be considerate and if you see cars behind you pull over and let them pass.
What a horrifically unacceptable attitude.
Certainly in the UK, if there's a 30 limit, there's a 30 limit for a reason. In that bracket of speed limit, it is more important than in
any other to be at
or below said limitation. If everyone's going 40, they're all a bunch of retards - and if you join them, you're one too.
Yes, I break speed limits, but I do it out of town, in quiet areas where hopefully there aren't any other people around, let alone traffic. But to speed in an area where a limit has been set specifically to reduce the potential of casualties (as 30mph limits usually are), that really pisses me off.
Ok, the main issue here I'm getting at is safety rather than speed, but it's proven - no, it's common bloody sense - that at 30 you're far less likely to kill that small child than if you're going at 40.
It's not
safer to do 40 in a 30 because 'everyone else did it'. That wouldn't fly here, you'd all get done for it.
