No it isn't. Published stopping distances are based on averages under

The ones in the highway code also seem to assume that you are driving a
Moris 1100 with crossply tyres and non servo assisted drum brakes.
(which since the published numbers have not changed since that may have
been the case is perhaps not surprising)

I was working on one project which involved the occasional trials
session over at the TRL research labs site. Some of the guys took the
opportunity to play with some of the measurement gear on their own cars.
They found that even the most mundane modern family cars could stop in
less than half the distance presented by the highway code.
