Yep.I've seen many impatient drivers and this one takes the
cake.It's a white Scooby and he flashed his middle finger so
passionately that he was pounding the interior of his RH window
with his fist.
Say around 1015pm?Somerset Road.He happened to be behind a green
Toyota who was just slowing down to turn into the carpark.That's
when he revved and rounded the Toyota, stared at the latter and
pounded his middle finger five times.
tsk.Such impatience is really uncalled for.Not to mention the
disgrace he has placed upon real motorsports enthusiasts.Many of
these rally cars, I've observed, have drivers who are either too
quick to horn, spew expletives or flip the bird at anyone who is
slower or happens to obstruct their whole show-off sequence down a
busy city street. 
You'd never see a Delta Integrale or a Maserati driver flip birds
like burgers.
