From my (long) experience of Italy and Positano I agree with Geoveo:
"Many of the local drivers are impatient, discourteous and downright dangerous. The tour buses bully there way through rarely giving way and the tourists meander along."
It's just so that the local drivers, regular and tour bus drivers, are obliged to drive on that road to do their work or to go to their work.
When they are delayed by tourists who "ignore anybody who drives in your boot" they get nervous and try to overtake these slow drivers under very risky conditions.
If you want to make friends in Italy avoid ignoring the local traffic bad or good habits.
Ciao.
