Who rents a car an doesn't read the manual? - almost everybody
Car manufacturers have had standards for a century, including door handles. Users of a product have a reasonable expectation of things to follow such standards. Tesla designers chose to deviate from such standards and people died.
It's pretty easy to tell if any car, owned or rented has an E-latch. If you pull a lever to get out, it's manual. If you push a button, it's electric.
I haven't rented a car with an electric latch, but you can bet if I did I'd look up where to find the manual release.

Standards change. At one time the cars to which you refer, had no crush zones, metal dashboards, no seat belts and no safety glass. Modern cars that have electric door latches always have a mechanical back-up.
Let's keep in mind that these folks got drunk and high, then got into the vehicle and crashed into a tree at high speeds. The driver had a BAC of .195, over twice the legal limit.
I'll bet the girl's parents aren't suing the driver's parents even though he was drunk, high and speeding.
