Yeah, he'll soon gain loads of confidence with us truckers to play with.....
Higher speed limits on motorways are all well & good, until joe public treats the new limit as he does the current limit.
He'll completely ignore it, and assume 110 ish is quite safe. (usually, regardless of conditions & traffic density)
Imagine the concequences of a blow out at 110mph, or, having to do a full stop from a similar speed if something unexpected happens, face it, you won't stop there will be a nasty smash.
The current limits are there for one reason only, our safety.
The fact modern cars can easily do well in excess of the limit is neither here nor there, todays motorways are no place for high speed, well, imo not with the current average driving ability I observe every day from any number of vehicle types, old & new, car & van, truck & bus.
