I just find them so unnecessary. If you need them for fuel efficiency, is your battery / motor / whatever really properly designed? It just comes off as desperate.
They do it because it looks cool and futuristic. Just like replacing all of the physical switches with non-tactile touch-based things. Overall just reduces the vehicle's safety and increases the cost to repair. Door handles, by law should be mandated to be physical things. If you want a button that can automatically actuate the physical linkage that's fine but the handle itself should be a physical linkage to the latch.
> The flush Hyundai and Kia handles are motorized and retractable, but they can also be opened entirely mechanically without power. They are little more awkward to use when unpowered but it's entirely doable if you know how. You just push the front side in which pops out the rear grab handle part. This also how Chevy has done their Equinox EV handles which is powered on the higher trims but unpowered for the base model I believe.
So, as long as they fail safe, I think they’re fine from a form and function perspective. It’s the failing unsafely (Tesla) that’s the problem. If they do not work without power, they should fail safety testing.

My example of seat belt pretensioners wasn’t to demonstrate when the action would be taken, but that pyrotechnics and vehicle dynamics are components of orchestrating a controlled failure mode in the event of a crash.
> General Motors Co. has since made the Corvette door’s emergency release handle more visible, the company said. Graphics on the handle, which lies on the floor next to the door, illustrate its function. GM also has added a “bystander access” feature on its e-doors to unlock them after a crash, so first responders or good Samaritans can free the occupants.
> Stellantis NV engineered a similar system on Jeep and Dodge models with electric doors, where airbag deployment automatically unlocks all doors. Stellantis and Ford also have outfitted their electric doors with supercapacitors that act as a battery backup to keep the power flowing to the latches even when a car’s 12-volt battery has died. And Ford, in response to this year’s recall, updated the software on its Mach-E to keep electricity flowing to door handles for 12 minutes after the small battery that normally supplies them — separate from the electric car’s main battery pack — goes dead.

But I guess I'm just, um, cranky.
