Man Gets “Trapped” In Hot Tesla After Battery Dies As He Wasn’t Aware Of Manual Release (www.carscoops.com)

From the article:

The man is blaming the automaker even though the manual door opener was under his left hand the whole time.

A man in Arizona says that he was recently trapped in his Tesla after getting in, closing the door, and then realizing that his battery was dead. What he didn’t know is that the manual release for the door was under his left hand the whole time. Now, he’s blaming the automaker and raising awareness.

Rick Meggison, 73, says that Tesla needs to address what he calls a “safety concern” involving how to exit the car when the battery dies. The main door latch actuator on all Tesla models is electronic so if the 12-volt battery dies it won’t work. To ensure safe exit of the vehicle Tesla includes a manual release. Meggison didn’t know about that and ended up trapped in his car for 20 minutes on a hot day.

“I couldn’t open the doors. I couldn’t lower the windows. The computer was dead, so I couldn’t open the glove box. I couldn’t open anything,” he told ABC7. Of course, he could’ve opened the door in about two seconds had he known that the manual release was just ahead of his window switches. His situation has many wondering who’s to blame in situations like this.

Genuinely curious, how much savings does that accomplish? Something as small as a door handle doesn't seem like it would create a lot of drag, but it might just be unintuitive

[-] madcaesar@lemmy.world 1 points 2 years ago

It's bullshit. They'd save 1000x more in range if they fixed the shitty gaps in their paneling instead of doing away with door handles.

Just because it's new doesn't mean it's better. Reinventing door handles is something no car needs.

I seriously doubt it changes much.

Hypermiling is a thing where people try to get 100 mpg from a compact car like the Honda Civic. It's been around for a few decades now.

There are things you can do to improve aerodynamic abilities of the car. The biggest is the wheel shrouds and overall car shape (nose and tail). Then you're covering up seams in the body work. I've not heard of anyone swapping out or door handles.

I'm sure the cause drag, but there is so much lower hanging fruit to address before changing something that small.

I honestly don't know, there does seem to be some controversy around this but Tesla seems determined to want flush handles so there must be something to it.

[-] wahming@lemmy.world 1 points 2 years ago

So, it might just be aesthetics then?

[-] Kushan@lemmy.world 0 points 2 years ago

It's definitely not just aesthetics, but the impact is up for debate. Tesla aren't the only EV manufacturer doing it.

[-] wahming@lemmy.world 1 points 2 years ago

If there is no data, how do you know it ISN'T just for aesthetics? It certainly seems that way.

Well, I did some googling and found this:

According to Amey Vikram, a lead analyst at Technavio for automotive components research, “The retractable door handle design allows radical aerodynamic designing for the side body panel. Retractable door handles are invisible handles that contribute by about 12% to reduce the drag coefficient of vehicles. Retractable door handles eliminate the issue of airflow bulge creation, air flow turbulence generation, and air flow pressure conservation. The decreased drag coefficient will also contribute to increasing the fuel efficiency of vehicles as there will be low drag generation resisting the movement of vehicles through the airflow.”

Seems like there is indeed plenty of data.

The impact on drag at normal highway speeds is negligible, there is no debate. It is entirely for cool factor points. Nothing accomplished by retractable handles couldn't be done better, cheaper, and with fewer moving parts with a standard handle.

errr, yeah there is debate. Given that nearly every EV manufacturer is doing their darnedest to flatten or remove door handles, don't you think there must be more than a "negligible" impact?
