Ya, first day I collected my car, I was like "o sh*t! why I
spend so much money to make myself stress". 1 week later, I started
tailgating people liao. 2 months down the road, first accident. Now
safety driver! Learn the hard way, you will never forget it!
Heehee! Actually just remember to check blind spot. I gotten dozens
of horn for that, was then that I realise a whole 2litre car can
squeeze into my small blindspot, totally disappear. My friend
wasn't so lucky. Didn't check blindspot can kanna a motocycle. Poor
dude fracture his arm, and my friend scare until blur! 
Anyway, start slow. Do some test-driving first. It is free and also
inline with your objective. I test 3 cars before buying.
