Typically "sporty" and some upscale/lux vehicles will but it's mostly a novelty item to make people feel like they're driving a race car. Unless equipped w/an SMT/DCT or an auto that lets you defeat auto-shift (some paddle types), there is no point. Most paddle autos w/a torque converter will still autoshift if pushed hard even in "sport mode". I suppose if performance driving and you've got a good sense of shift points and power band, you can make an argument of wanting to know where you are to avoid upshifts or kickdowns.
Dunno, my very cheap Hyundai has a tachometer. All automatics I've driven have tachometers except for CVTs, so maybe you mean CVTs? The Tiptronic/DCTs I've driven do auto-shift to protect the gearbox.
A tach in a manual is part of the driver feedback loop when shifting. During auto vehicle development a tach is obviously a necessity for shift map setting but once the shift map is baked in, there's no point. I hate seeing an empty space where the tach should be and I suppose most drivers as well. If there's a manual version of the vehicle available, with economies of scale they've become more common place in autos. If drivers get a feeling they're getting something more premium, OEMs will take the plunge. Lots of shit is for the psych factor but most autos I've driven (only owned auto pick ups) have been tach-less I could see perhaps a need if towing, cruise control, passing and driver being inhibited from doing something because outside of some RPM band. Handy in diagnosis/troubleshooting too. with lots of LCD displays out there, a tach is just a few extra megabytes of code.
Objectively though, if 2020 was the last year this warranty was offered, and it's 8 yrs (at most generous; model S launched in 2012), this dude is driving 125k/yr at a minimum. Does he work for a testing firm? Kudos to tesla for making an EV that's long term viable (curious about degradation of batt @ 750k mi) but you can keep plenty cars on the road replacing engines every 111k miles; an analogy that is apt now that tesla no longer offers said unlimited warranty. I'll echo what another poster said, the beauty of electric motors is long term durability (no idea if this is a dual motor model), what most impressed is the batt life.
Tesla's motor has gone through various iteration since that guy bought and drove his car 1 million miles. I expect the newer one is more dependable in addition to being the most efficient to date on high volume production cars.
i'm not watching an EV video clickbaiting w/a jet engine in the thumbnail. Efficiency in EV motors is kinda "whatever"...I expect 90%+ out of most at this point (Tesla's isn't reinventing electric motors as much as they want you to believe). Inverter and batt. tech is where you'll get my attention. Tesla's Aero team's done a good job maximizing range. Monroe does a good job w/motor breakdowns though he simps for Elon and is more of a "packaging" guy. I like this video:
sure, but I'm talking amongst electric motors. The things have been around forever and are basically approaching a point of diminishing returns efficiency wise; I understand you want to squeeze the max amount of range out of the things but there's other places where you can find that cheaper (heat pump for instance). Innovation on the materials side is exciting though: https://newatlas.com/automotive/mahle-magnet-free-electric-traction-motor/
