I just want to make sure that it is not a must that a 9v battery be placed in its load battery holder - considering it is hardwired and the 9v is acting as the backup. Note: This is only going to be done for 1 of 6 detectors - as it is in a hard to access location. All others will have 9v batteries placed in them.
They force people to slow their speed. I would assume if you go over a speed bump, especially the skinny ones, you are risking damage to the car. But people should just slow down when coming to a speed bump anyway. It's obviously there for a reason.
Skip the speed bump, it?s really not worth it. MacBooks are not great for gaming, but they will do.
