This often happens with Hondas, because there is no check for Speed Breakers. Any Tom, Dick & Harry can get a Speed Breaker made in front of his house without any permission or check, therefore most Speed Breakers are unusually high or stupidly made.
After having in a CNG cylinder, one should get their car's a bit higher from rear. Because when loaded with passengers, car gets even lower of course. And it is bound to hit the Breaker.
