>>28522859 (OP)>Engine brake also damages your engine lmao.Thats false information unless you make mistake of downshifting gear from high engine RPM's, too high driving speed for the lower gear.
>loud as fuck.Not in normal cars or properly tuned cars. If you downshift a gear when engine rpm is near the idle RPM like 1000-1300rpm.
>the person behind you has no idea you're slowing down.The driver behind you is blind or distracted idiot then. Every driver who truly pays attention to his/her driving can see if you begin to slow down. it its fairly easy to notice if you are driving behind other car, if you know your current speed, if you first have been driving same or lower speed than the car in front you for longer time, then you suddenly approach/get closer the other car abnormally fast, like a 0.5-1.5 second faster than you estimated despite you not increasing your driving speed at all. Thats one way how you can sense that other car in front of you has slowed down despite brake lights or tail lights not turning on.
