Husky,
the idiot truckers on the A34 move over to block the outside lane of 2 and usually end up pulling back over having passed nothing, as if there was anything on the slip road it's already pulled in front and disappeared. This leads the the need for trucks to be banned from the outside lane of 2-lane d/c so that traffic can move at a decent speed (and i mean somewhere near 70, not warp speed) but that again relies on the muppets pulling back to the left after passing something, not thinking the outside lane is for doing 60 because there's another truck 1/2 a mile ahead.
Most days the A34 is single file all the way from the M40 to the M3 and the same on the way back
Agreed, with the speed of the Zed you should be able to match speed for a gap long before the end of a motorway slip road. If it'sa short slip road onto a 2 lane d/c then the speed limit on the d/c is probably too high.
Don't get me started on the Coventry ring road with the on-ramp being the same as the off ramp for the next juction
