Default Why isn't manual transmission used on railway vehicles?

Except the Stig himself knows that electronics do it better. The only
reason F1 cars have flappy paddles is because the full-auto option is
banned. Barnard did the semi-auto for his Ferraris in the late
eighties, because powered shifting and automatic clutches were enough
of a problem, but rapidly other teams realised that the real win was a
full auto, and Benneton and Williams were both running fully automatic
gearboxes by the early 90s.

Remember, the great F1 car that never was: the Williams of 1993 with a
CVT gearbox, tested by Hill and others. It was two seconds a lap
faster, straight out of the box, with the engine not yet tuned to take
advantage of the fact that with CVT a power-band 1 rev wide is just
fine. It was banned instantly, and criminally, mostly on the grounds
of the bizarre noise it made and a fear of a transmission arms race.

Full-auto gearboxes were banned in the post-Senna hysteria, and hence
the rise of the flappy paddle. But it's bollocks to think that's a
good thing for your Stag about town: it's a regulatory issue, which
stops the teams doing the faster thing.
