  In our Canadian city, the speed bumps have breaks that allow wide-axle vehicles (buses, emergency vehicles) to pass with minimal braking[0]. Some large passenger vehicles can get through the same way, but for most vehicles it's a speed bump. The issue with speed bumps is that it's just not a good traffic calming design. Why should a vehicle slow down to, say, 20 kmh at random spots when the limit is 40 kmh? Traffic tables[1] are much better, in that if they're properly installed, you don't need to slow down if you're already going the speed limit. They should be installed at pedestrian crossings to make the crossing level with the sidewalk (cars go up and down) instead of being level with the street (pedestrians go down, then up). The street should be narrowed at pedestrian crossings too, and at all intersections (no parking there anyway).
