         | in the article, it shows a Magna-Steyr handle on a Mercedes
         | Gelaendewagen, which looks like those on the Ineos Grenadier,
         | and not very different than the ones that Ford uses on various
         | trucks.
         | 
         | that contrasts with those on Audi and BMW evs, for examples i
         | see often, where the CoD is a stated spec for ev shoppers, and
         | the handles have motion to them, but are flush (but not Tesla
         | vanishingly flush). Weirdly, some Porsches (intimately related
         | to Audi...just read the shared parts) use flush handles and
         | some the protruding handles with an actual handle.
         | 
         | i admittedly pay an unusual amount of attention to car
         | componentry, sort of a hobby really.

           | Flush handles exist as brand differentiators. They're a
           | "futuristic" feel-good feature that consumers want, like
           | engine noise, tablets, and colorful dashboards.

             | These are not in conflict. The energy you save from drag

               | I have a car with a "novel" handle situation. (Ford

               | Manufacturers went on an aerodynamics optimization spree
               | in the 80s after the fuel crisis. Concepts like the Ford
               | Probe actually dropped handles and all other protruding
               | surfaces in favor of things like electrical touch panels.
               | Seriously, go look at the photos. Even the pillars are
               | flush.
               | 
               | The production vehicles designed after these concepts
               | often used flush pull-up handles for aerodynamics. Those
               | handles later disappeared in favor of the more reliable
               | pull-bar handles we're familiar with because improved CFD
               | made it clear how minimal their benefit actually was for
               | the tradeoffs.
               | 
               | Of course, even if we accept that all the mechanical
               | complexity of flush handles is necessary for aerodynamic
               | reasons, it's not the only alternative to pull-bars. Look
               | at the Volvo EX60 for an example. Designing a flush
               | handle is hard. Tesla spent years working on it. It's not
               | something undertaken for negligible aerodynamic benefits.

               | easier to meet because they're secured on both sides.
               | 
               | The pull-up latches also caused issues for people with
               | long nails. In some places spiders liked to nest inside
               | them. Places with snow had issues with a sheet of ice

         | Electric door locks are bad, too. After a while, they won't
         | lock or unlock.

       | When I was about 20, I had a well used AMC Spirit.

       | Stylish, good gas mileage, decent performance, it was a great
       | car. It had one fatal flaw, a weak linkage in the drivers door
       | handle.
       | 
       | The linkage included a small plastic clip that didn't quite align
       | properly. It would pop out of place periodically, making the door
       | impossible to open. I became adept at taking apart the door from
       | the inside and popping the pieces back into place.

       | I once returned to my college dorm after a snowstorm, the car got
       | stuck in the snow. I had another trick for this situation, I'd
       | ease the clutch out ( leaving the back tires spinning slowly )
       | and would exit the car, pushing it by hand. When the wheels
       | caught and the car started creeping forward I'd jump back in and
       | drive off. ( Foolish, I know. I was 20. )
       | 
       | Well, once I had both mishaps at once. The car got stuck, so I
       | got out to push. The door handle broke, locking me out of my car
       | with the engine running and the wheels slowly turning!
       | 
       | Praying fervently, I ran to my dorm room, got my spare key and
       | went in through the passenger door to stop the engine.
       | 
       | It was a memorable day.
