Picture ain’t mine but in the last decade in my country, there’s more and more motorcycles than ever before, mostly because they’re cheap and plentiful, and while they supposedly level the playing field in terms of private vehicle ownership, they also affect other people like cyclists.
Let me give it the good ol’ “it depends”.
The main problems with traditional motorcycles are that they’re louder and dirtier than cars, but both things could be solved with electric motors.
But aside from that, they’re basically better - or less bad - cars. Granted, I’m not in a scooter city like those in south east Asia, so I might be missing something, but I believe 1-2 Scooter parking spaces per household is more realistic than 1-2 car parking spaces and 50 people on scooters can move through an intersection quicker than the same people in cars. In a crash, they’re way more likely to kill or injure their driver than a car, but less likely to do that to the other parties.
I think they’re fine.
modern ones have catalytic converters but use far less fuel than any car. 100mpg is normal.
