Speed bumps

Don't mind me, I'm just making sure you go slowWhy is it that people will release the brake pedal right as they get to the speed bump? Never a moment before or after, but right as their front wheel is about to go over it, and then just hope the car has enough momentum to keep going. Everyone I’ve ever observed does this. It’s like the axle will somehow break if the brake is still on when you go over the bump. The back wheels don’t matter for some reason. I mean you never see anyone brake after the front wheels get over the bump. Once the front of the car and the driver are over, the rear axle doesn’t get anywhere near the same love.
