Tesla will arrange recovery to the nearest service station in the event of a (probable) warranty issue. If the place is shut, I think they just dump it outside. You have to find your own way home.
Tyre issues are also hit and miss, they may do the above, up to something like 50 miles, but again, have the problem at 10pm on Sat and it’s Monday before anyone will look at it. They may also say no, it’s accident damage if its from say hitting a pothole.
I therefore think it comes down to how risk adverse you are. The safest route is have 3rd party relay cover, the next is be prepared to get your credit card out if Tesla are a problem if you hav3 a basic cover with sa6 your bank account, the most risky is rely on Tesla without any means to bail yourself out if needed.
For what it’s worth, in the UK I do the middle option, rely on Tesla and be prepared to top up my bank account cover if the worst happens. When I toured Europe I took at full cover.
