As more people get EVs - it's unreasonable to expect everyone will follow any type of etiquette or understand how the charging works on other vehicles. If their car has a status light while charging and your car doesn't, it's not unreasonable for the other driver to assume your car is done charging. And, unfortunately, many drivers will stay connected long after their cars have finished charging.
Tesla should do two things to address this:
- If not continuously, at least periodically (once a minute?) flash a charging status on the port. Though since the charging status lights don't take much power, there could also be a setting to allow drivers to keep the charging status light on whenever the car is charging.
- Provide locking J1772 adapters, rather than relying on 3rd parties, with uncertified adapters, for this solution. Or, Tesla should have a program to certify 3rd party adapters - and then include those in their online store.
We should expect this situation to get worse as more manufacturers begin selling EVs...
