Switzerland is actually a dream for car-free living. You only need a car if you live in a rural area. Taxes are pretty low. There a bunch of mandatory insurances you need but my experience was your net income position was substantially better than being a salaried employee in London (although food in particular is MUCH more expensive in Switzerland such that people will drive an hour to Aldi across the border in Germany to go shopping).

Fun fact #1: there are limits to how many groceries you can bring into Switzerland. Meat in particular. You can get checked for this at the border.

Fun fact #2: IIRC years ago the supermarket just across the border in Germany had the highest revenue of any supermarket in Germany.

As for work authorization, it is relatively easy for EU citizens to get and somewhat harder for non-EU citizens. It generally takes 5 years on a B permit (work visa) to get a C permit (permanent residence) if you're EU, 10 if you're not.

I imagine with Brexit, UK citizens are now in the harder category.
