So it's not quite as clear cut that all the extra safety stuff makes
people drive less carefully :-)


It is, though. The taxi driver ABS trial was a near-perfect
double-blind study and it showed that those driving ABS equipped cars
accelerated harder, braked harder, drove faster and followed closer.


What particular form of psychic capability was reckoned to account for this,
then ? As soon as any driver realised his vehicle had ABS, the trial failed
the double-blind test, which demands that those taking part and the
observers are both ignorant of the conditions.

(I don't have any problem with trials that show that drivers fully aware of
such features may "risk compensate" for them. But claiming to have
double-blind trial results smacks of very dodgy science.)
