Designing solutions where there's no problem ...
.... how often do we hear established entrepreneurs with serial successful businesses say this is what you should avoid (lots of episodes of Dragons Den for a start) .... falcon wing doors, hermetically sealed cabins ....
The S can get away with it's £90k price tag (yes I know it starts at £58, but try adding those things basic in other cars - I priced one up as there's a Tesla garage round the corner from where I work) as it's targeted at other cars in the same sort of price range. This is up against cars two thirds it's price - it's just too much (assuming a suitable charging network is available to you).
And for those who think the falcon wings solve a problem - have a look at the good old (well not so good in reality) Peugeot 1007 where you have a better solution with no headroom or reach out room requirements.
