I always give hand signals. But frankly I get stare from the other motorists and cars, with an inquisitiveness to know who in the hell gives a hand signal in present day driving.. bangalore is full of morons. Even in highways no one gives hand signal nowadays and trust me that causes many accidents.
All my childhood we had to travel in highway each side 15 kms, and at an approximation, I watched an accident every 2nd day. All because a proper signalling was not done
