It's because Tesla has so few models. Every other manufacturer has an order of magnitude (or two orders) more models you can buy. Some brands have more EV models than Tesla does.

The Model Y looks a lot like the Model 3.

Took me maybe 50 cars of training to learn to recognise the difference when passing Teslas on the streets.. but now I finally do! :)

i live in amsterdam and i see teslas literally every day.

hell, a guy parks his tesla in front of my house daily to use the public charger.

There are a fair few of them in London, mainly model 3s I think.
