Is this really news?

So if I get locked out of a car, I'm suddenly worthy of making headlines? There are bigger things to draw attention to than this.

Not if you lose a key, of course. But getting locked out over a mechanical failure that happens often (a dead battery) is newsworthy. This seems to be yet another serious design flaw.

Any other car has a physical key as a backup. If the battery dies you can use the physical key to open it up and pop the hood to get to the battery to charge it.

With a Tesla you can’t do that because they don’t have a physical key.

You don’t need to pop the hood to jump the battery, there’s a manual latch on the front that works if it’s dead. This isn’t news it’s just clickbait Tesla hate.

The article itself says the owner tried to jump it several times before having to get it towed… like he would have for every other car brand.

Meanwhile my Hyundai Ioniq not only allows you to open it with just the physical key, it also has a button to charge the 12v portion of the battery off of the larger hybrid battery

Teslas automatically keep the 12v topped up from the HV system. But like any car battery they can die and eventually won't take a charge at all. What they should so is have a bypass circuit you can activate to let the whole 12v subsystem pull directly from the HV system as long as the car is not in drive. The issue is that the HV battery needs a physical disconnect in an accident which is why they have the 12v battery in the first place.

That would suck. It’s like when it’s so cold out cars can have issues starting, but at least you can get inside. You’d think if the 12v battery was dead on the Tesla you could plug it into a charger on the outside of the car. Maybe a feature for a future model.

This is the case. The car has an external jump point.

Correct me if I'm wrong here, but from a safety perspective shouldn't this mechanism fail open? Especially given the fact that I don't believe they even have a physical key, it's only the electromechanical locking mechanism
