There is a lot of truth to this. If internal combustion engines were being rolled out today, people would be discussing those downsides. But, ICEs have been with us for quite some time, so we've accepted the downsides and mitigated where possible. This happens with anything that is new but competes with something that is old.

Personally, I am strongly rooting for Tesla. Even is Tesla fails, they will have significantly changed the automobile landscape.
