But the Tesla is still extremely expensive compared to most "little" cars in my UK neighbourhood (VW Up!, Toyota Yaris etc.)

I see many secondhand cars here and can't understand how the 100,000 mile warranty on batteries (eg the 100,000 miles quoted by the VW ID3) will ever compete with secondhand combustion engine vehicles. For a VW Golf, a 200,000+ mile limit is "normal". I can't see how the removal of the floor to replace the batteries will ever work in practice, unless we're making all these cars with a short-sighted view of recycling?
