Enforcement needs to be on the sales side, as enforcement at the consumer level is obviously impossible to scale. Also, class 2 (and 3) should not be allowed in bike lanes. If you have a throttle, you're not a bike; you're a motorcycle or moped. I see a clear difference in awareness and safety between pedal and throttle usage.
