The problem is that these things only seem more dangerous. At the end of the day, momentum kills. Speeding in an automobile, especially in urban areas, is far and away the most dangerous thing of any of the "crimes" here, and it's treated as though it should be expected, not reprehensible as it is.

A cyclist yielding at a stop sign isn't going to kill anyone. The car flooring it after each one and rolling the crosswalks may.
