they also had to redesign the door handle and people have gotten stuck in the cars because of that and died. not just one isolated incident... more than one case of the car door not working because it's electrical only and the backup physical release mechanism is under a door panel you need to pop off and reach inside to pull after you just got into an accident and are physically disoriented.
Look at that door handle. Fully flush, NACA profile scoop in the bodywork to insert your finger behind the trailing edge of the door and flick the little lever up to unlatch it.
Give me that, please. I wish I'd never sold my 1991 Citroën AX GT, it was so quick and quiet. Hardly any wind noise, so it must have been very aerodynamic.

I can't help but think that the water pump must require about 3 brake gerbil power to turn, and the weight of the solenoid, plunger, spring, shroud, and extra cabling - not to mention more seals to go hard and leak - probably takes more power to haul around.
I don't really care about a car's 0-60 time or fractions of a mile per gallon. If you want to save fuel, lighten your right foot.
I want the car to be simple enough to be reliable and repairable when it eventually does go wrong.
If you really wanted to not run the coolant pump until you'd got the engine a little warmer I would have thought a magnetic clutch like an aircon compressor would have been better. Although these days, maybe even an electric pump could be more efficient.
I’m not familiar with the impeller shroud you mentioned, but I looked it up and the description seems to agree: “This pump includes the shroud and control valve to restrict flow while the engine heats up.”
Whether or not it affects the time required for the heater core to be operational would depend on how they decided to route it, and if the solenoid offers variable positioning. I imagine it is variable, otherwise they’d create thermal shock every time the engine heated up and the pump suddenly started flowing colder coolant through the block, so technically it should be possible to fully replicate the general functioning of the thermostat and heater core. Now that I think about it, it’s most certainly variable and it’s why they didn’t go with a clutch system.
I hadn't thought about the thermal shock thing but I did wonder how it could possibly help the coolant warm up if it's not circulating at least through the block. The engine doesn't warm up evenly.
My only other guess is that it’s not 100% on/off, like maybe a bit is still allowed to flow when “off”, but then it would still need to bring the entire coolant mass up to temperature so I’m not sure how that would be a benefit for faster warmup. Either there’s some clever engineering I’m not seeing, or you’re buying a few points of regulatory compliance for them by needing to replace head bolts and gaskets sooner.
(mostly design clout though)
You don't need a tacho. Some people add them in, like the Mini dashboard in the pic below, but they are absolutely not necessary. We managed fine without them for long enough.

There you go, 1970 Mini, it's a 1275 version so it has an oil pressure gauge and an aftermarket rev counter.
Does your modern car actually *need* anything more exciting than that?
Compare these:
1982 Volvo, like I bought after I passed my driving test in the early 90s:
https://autopecas.norsider.pt/content/images/thumbs/136/1365...
2004 Range Rover P38A similar to the '97 I drive now although this is a NAS-spec cluster (like with the "unleaded fuel only" placard):
https://www.rangerovers.net/attachments/smartselect_20210517...
Notice something? Both have the fuel gauge, Volvo has a clock but posh models had a tacho, Rangie has a tacho, then both have the speedo, then the temperature gauge.
The Volvo has the idiot lights along the top, the Range Rover has them along the bottom - and in the middle a 20x2 LCD (which in that one looks a bit worse for wear) which shows the odometer, gear selection, and occasionally lies about fault conditions.
Doesn't it remind you a little of how aircraft have a standard "Six Pack" layout for the flight instruments?
We should do it this way.
I wish I still had it.
So many of the mechanical controls of that car felt like working the action of a very, *very* expensive shotgun.
EDIT: I just remembered the shock absorbers in the front bumper. IIRC in the owner's manual it said you can crash into things at up to 5mph with no fear of damage. I never tested that.. A Subaru did run into one of my fenders, though. The fender was bent in at the wheel arch maybe 3". The poor Subie suffered a punctured A/C condenser, radiator, and the plastic bumper shattered. I yanked the dent out of the fender (more or less) with a prybar and drove away. The Subaru went home on a rollback.
Somehow a small amber light (in the shape of a fuel pump) and a chime has worked for decades and there haven't been hordes of drivers stranded as a result. Something your grandmother could easily understand.
10-15 year old cars maybe give an additional small information message in the cluster easily dismissible with a steering wheel button.
No, the problem has been the mass importation of tech industry rejects into the car companies, as if the car companies haven't been quietly and successfully writing embedded software for 50 years, who brought their terrible habits with them. Like a need to "reinvent" UIs every six months.
Cars are safety-critical machines. They are not a place for "creatives" to experiment with UI design.
Sadly marketing drones think everybody wants a Tesla-style "everything is a screen" design whereas a 1999 Toyota pretty much had it right.
This isn't difficult. It requires no "innovation". Analog tach and speedo with idiot lights for critical alerts (there is literally an ISO standard for this) should be mandated by law. Substitute tach for a battery monitor in an EV.
EVs are the worst of both extremes. Either the entire interior is a touchscreen or you have something like the Slate, where there isn't even a radio. A room full of geniuses and what they come up with is a bluetooth speaker holder. Unbelievable, you can't throw in a DIN radio like a 1987 Datsun? Why can't EV manufacturers build a "normal" car?
