I know what you mean.
I hadn't driven for some time until now and am regretting buying a car.
I'm hoping there will be a lot less traffic in Tasmania to worry about compared to northern NSW.
If it is just as bad I sell and stick to buses and tours.
It's funny how people change when behind the wheel - if you're walking in a crowd and accidently bump into someone, invariably you both will say 'sorry' despite who is at fault yet when on the road you'll blow your horn and mentally abuse the other driver.
We all make mistakes on the road so you've just got to live with it. Attitude.
