I can't work out why we have such a problem. Over 30 years of holidaying
in the North of France (Brittany) I have driven along one particular
road that has dozens of large rectangular patches to the surface. They
are so smoothly joined that you don't feel anything as you go over them
and in 30 years they haven't deteriorated.


And the attitude to speed humps in this country is ridiculous.
No way can you drive at anything like the speed limit over
these obstructions, so what's the point?

Tfl say that the maximum gradient of a speed hunp or table son
a bus route should be 16:1.

This is a bus route that I used to use daily - what's the rate
of attack here?

The leading edge rises to pavement hieight at nigh on 1:1!

I've driven a lot abroad, particularly in Belgium and I've
noticed that if the speed limit is, say, 70km/h (~42mph), you
can drive over a speed bump at 70 with no problems.

I only ever had a problem once when one gave me a bit of a
jolt, but that was my fault as I discovered the followeing day
that I'd missed the town boundary marker obscured by trees and
it was actually a 50km/h limit. I dropped my speed to 50km/h
(~30mph) and no problem.

Proof posiutive to me that, correctly implemented, they can
and do warn speeding drivers without impeding the normal
traffic flow.
