Less dangerous to others, but more dangerous to the users themselves, I suppose.

Hit a pothole going 25mph in your car. Hit the same pothole going 25mph on your scooter. I'll come visit you in the hospital after the scooter one and we can talk about how cars are obviously safer.

I ride an electric scooter, all it takes is one crack in the road that I'm less than prepared for and I'm going down hard.

They are more dangerous exactly because of the existence of cars. Cars are a small fortress that makes others less safe while keeping its contents safer. Unless they hit another fortress.

Heeeeell no. I had I minor fall on a scooter last week. I slipped at medium speed because of an uneven wet floor. I'm still fucked up and can't walk properly

motorcycles should 100% be in the zone of practicality, especially with modern sleek electric ones.

skateboards should be the bridge between practical and recreational, provided you have sensible infrastructure and short distances they have distinct benefits.

skis and sleds just need snow to make sense

But hardly for hot air balloons

Trust you on that but will ski across the pond to check and be sure

also a fun fact, while commercial aviation is very safe, private planes are much more dangerous, being almost as dangerous per mile as a regular car (and you get a lot more miles per hour of travel)

That’s not true. When I drive I still hate drivers

You'd need to normalize the number to deaths per balloon ride.

Also, only less convenient than cars because of cars

I'd guess it's because unicycles are used in a much narrower range of circumstances. Few people are being hit by cars commuting to work on a unicycle, nor are there many mountain-unicyclists getting injured.

I think it means more dangerous to use, not more dangerous to be around.

Those first two are incredibly fit for some niche that is so small that nobody even remembers it exists.

The last one is still more practical than hot air balloons.
