If people can do short journeys on a bike instead of a car then it's much better for everyone, really. Plus they're good for those with long term injuries or those who aren't very active to start an active life style.
I try not to be snobby about them but I do harbour a bit of snobbery about them when the rider says how fast/far they can go as if it's a badge of honour. But that's likely as I look at bikes from the angle of fitness and exercise. Suffering up a hill is a big part of the fun for me. I'm slow as molasses on the flats and even slower up hills but the satisfaction of the challenge is second to none.
Get an ebike and you can be even slower by adding weight and not using the motor. Win win!
