Why don't we see that many convertible EVs on the market and will there ever be aTesla convertible?
How about we just worry about manufacturing Model 3's before we even start thinking about convertibles?
To answer your question, I think weight is the biggest obstacle to making a convertible EV. Car makers are trying to reduce weight & drag; Convertibles need to add steel in the doors & side panels to increase rigidity.
Plus the market for convertibles is tiny. Still if you really want one, here is a company that does conversions on Tesla: http://newportconvertible.com/tesla-model-s-convertible/
The upcoming Tesla Roadster, while not a convertable, does have a removable hard top, as did the original Roadster.
Yeah, Roadster will fit the bill, time for you to make a deposit!
Aerodynamics would be pretty awful, too, which adds to range issues.
Even in sunny California I see way fewer convertibles than I do $100k cars.
Big safety impact too.
"safety" can sometimes otherwise be known as "driver negligence"
