its actually worse now, as many people that spent their lives driving in taxis, now get a car, and drive their car like a taxi.
gives credence to the fact that one learns road manners by who you saw driving mostly when you were younger.
so if you "imprinted" on a taxi, chances are you will drive like a taxi with your own car.
if you "imprinted" on "grandad" you'll still drive 70 in the fast lane and hog up the road.
if you "imprinted" on your boy racer brother/sister/uncle/aunt, chances are you will drive that way when you get a car of your own.
I think road rules and respect for them forms the first time you traveling in a vehicle.
whether that's in a bus or car, taxi or motorbike.
