I have biker friends who call cars "cages", and I get the sentiment. But they have a lot more concussions than any other group of people I know.
- stay within reasonable speed
- keep distance
- don't do highways
- project your intentions very clearly with no sudden moves
vast majority of accidents happen when this simple rule set is broken (aside from obvious DUI). If you're driving 40km/h max in a city you are surprisingly safe, especially as scooter traffic culture is very river like so once you're familiar with the area you are basically being carried by the traffic.
Most stats of SEA scooter deaths are coming from really bad driving, as in drunk uncle driving a scooter on the opposite side of the road with no headlights sort of bad driving (sadly very common). The culture can be very unserious about scooter safety when it's quite achievable in practice. It really is an incredible form of transportation when taken seriously.
Though it really isn't helped by attitude of people around here who aren't even wearing helms.
