Bullshit, more dangerous because of the other cars who are not used to having motorbikes nearby, and you have this idea of being less protected on a motorbike, in reality you should try to understand that on a motorbike everything is much more predictable and the problem is almost only who is riding it, in a car, you have more blind spots and less control and therefore greater risk of making mistakes and for pollution, seriously, the simple use of a motorbike when all the space in the car is not needed would eliminate almost all traffic on the road therefore less pollution, less weight to move, less wasted energy, motorbikes are better in everything and not they are only considered because of the comfort zone of the average person.
And noisy what the fuck means? even motorcyclists can be idiots and change the exhaust to make more noise, but this happens because having the fucking motorbike is a niche of people who adore and modify their motorbike, but you can very well not do it.
I know someone who died because he was irresponsible, I myself had 2 accidents, one of which was serious and I no longer ride because I don't trust myself or others, with the problem that I spend a lot more if there is no public transport.
It's a vehicle that gives too much freedom, and it doesn't take long for a person who isn't fully responsible to abuse what he can do on the road.
I was speaking more ideally, because if you limit yourself you can have all the advantages it can give without ending up between the sheets of guardrails and cars.
