Maybe offtopic, but why should we expect police to exercise discretion? That's how you end up with disproportionate crime being prosecuted in neighborhoods of color.
I think laws should be simple and enforced. For example, raise speed limits so they are high enough that nobody has a reason to routinely break them, then draconian enforcement. Old white Grandpa weaving around should get the same penalty as young Black guy weaving through traffic.
I don't disagree, but until and unless all laws (not just speed limits) are written with sensible exceptions and thresholds included, police and prosecutorial discretion are the only avenues we have to create a semblance of reasonableness.
