In reply to A Longleat Boulderer:
"Additionally I always get abuse in the form of tailgating, horns and flashing lights when I slop properly for speed bumps."
The best designed type are the "cushion" ones which in any vaguely normal[1] car you can traverse at or slightly below the speed limit, but you'd be thrown up in the air if speeding.
[1] If you have a chavmobile Corsa with lowered suspension, we can all laugh. If you have a proper, decent sports car, we might show some consideration
"I'm talking the 2 meter by 1 meter lumps in the road. I was doing about 15 mph and the other driver flew over the bumps with the suspension at full compression."
The ones by me of that type can be taken at 25-30mph, but not any faster, without any problems. I guess they come in various sizes.
"Chicanes for me too please."
"Natural chicanes" made using things like planters and car parking seem best. Or on new housing estates just design the roads so you naturally can't use them quickly - deliberately bad sightlines for other road traffic (but as good as possible for pedestrians), lots of bends and narrowing etc does the job.
