@Nimbupani....Absolutely true. Many many have little idea when to give indicators for taking an exit. They either give it quite early and keep going to the next exit, or they would give at the last second.

The big culprit here is their ability to master driving skills.

Just watch the police cars and ambulances drive through the roads. What makes you think anyone can drive like that? No way! They are trained for "tactical driving" skills.
