You should go faster, so he will tailgate you at higher speed. Then when near the speed trap location you slow down and let him overtake....This morning going to office via the KL-Seremban highway, I was tailgated by a silver Audi TT. I noticed this car for the 3rd time already going this same route in the morning and he always drives a bit fast and tailgated people. So this morning when he tailgated me again, I gas it a bit hard and left him for a hundred meters or so during one empty stretch, but maybe cause he just did not react or not expecting. Then once I slowed down due to traffic in front, he tailgated again. So I just gave way since it's also already close to a regular speed trap location and approaching my exit. Luckily, no police there to shoot too.
