Oh, look, another morphing fuckwit with nothing sensible to add.

The point I raised is actually a very serious one that a lot of people
work very hard to keep in the minds of legislators - that not every
vehicle on the roads is a normal modern boring hatchback. There's a lot
of older vehicles that could easily be driven off the roads by badly
written or enforced legislation. When even an ex-TrafPlod takes the easy
answer rather than think for a second, a reminder is sometimes needed.

Well isn't the vehicle tested on a rolling road for the brakes ?

Yes, but I doubt it goes fast enough to test a speedo

How does it vary a great deal in one second?
