Impatient and reckless driver

It's a gated guarded community. I slowed down as I approached my house, signalled to indicate a right turn as I opened my autogate.

My autogate opening.

I prepared to turn right, a car tried to overtake and honk at me. Startled, I slammed the brakes.

Now, what should you do when you see a car in front of you slow down and signal to turn right? Should you overtake?
