I would think its a little different since the infrastructure was already in place for gasoline. There isn't the same infrastructure nation-wide for electric vehicles.
Tesla is saying that even if you drain your battery driving, it would still take 30 days of failing to charge it to brick it. While the infrastructure for just "filling up real quick" may not exist for electric cars, the infrastructure certainly exists at a person's home, otherwise, they wouldn't buy an electric car.
I think there would be a much more compelling case for this if electric cars were being mass-adopted, and the education for maintaining them was poor. Neither is the case here. Electric cars are still largely in the early adopters phase, and Tesla is telling people to not leave their car unplugged for months on end.
Much ado about nothing.
I'm sure in the early days of gas-powered vehicles, plenty of engines seized up because people were unaware they had to change the oil and keep it at a certain level. And it certainly still happens on occasion.

Assumine new vehicles, doing nothing to a Tesla for ~30 days means $40k. Changing your oil 6 month later than the service schedule in most cases means inmeasurable (by owner) reduction in overall engine lifetime.
