sounding much like they were saying:

Since the 1960s car control has improved tremendously from power
steering through ABS brakes, yet the Highway Code still has the
stopping (thinking/braking) distances of old. I would like to see
these distances recast for modern cars with two tables, one for dry
conditions and one for wet.

The tables will continue to be current until all non-"modern" vehicles
are removed from the roads.

Even though the vehicles to which they are relevant are a _tiny_ minority
of those on the roads - and they are wildly optimistic for other vehicles?

This may come as a shock to you, but the tables never had anything to do
with real performance. They are a simple mathematical model linking the
speed in mph with the stopping distance in feet. Anyone with GCSE maths
should take no more than 2 minutes to deduce the formula that is used..
