Brushed stainless bonded to a fibreglass shell if I remember.

Hard to believe that anyone would look at data from road deaths/injuries over the years and suggest that older cars were, size for size, safer than newer ones. Not all the reductions are down to simply better car design of course but I’d wager that a good proportion of that reduction is down to better design, and the addition of modern safety features.
That's exactly the sort of thing needed, consumption adapting to available power rather than assuming we can draw whatever we like, whenever we like. But unless that's made mandatory and built into all chargers (is it?) or there's a financial incentive, then the guy with a non-adaptive charger is better off as he never has to wait for his charge.
I've also seen references to chargers that download next days pricing, for people on TOU tariffs where the price changes e very half hour. With the right tech you could tell the car/charger how much charge you want, and when you need it, and the charger would work out the cheapest times to get there.

Three phase high voltage motors and integrated inverters won’t have much in command with dc and thyristors
Yup switched reluctance motor doesn't really compare to a big brushed motor

It’s not that they couldn’t do that, it’s whether it’s the best solution? Would you add an extra component in the drivetrain with associated losses, complexity and maintenance requirements or just stick in a bigger motor?

Which probably costs the same in materials no extra assembly lines.
Plus you don't have to draw all the power all the time

It's not what I'd do, it's what the marketing department think their customers want who might make that decision.
I've a book on marketing failures somewhere, one of the case studies was a high end washing machine manufacturer who made a version of one of there machines with fewer washing programs. Customer surveys suggested that what customers wanted, the problem was not many people bought it, they bought the similar model, more expensive, but it had more programs.
The Daf 45 and 55 were seen as joke cars back in the day from what I remember. I can't comment as I 've never even sat in one let alone driven one.

When ABS braking became mainstream - bodyshop thru put dropped... That is a fact!

Probably a marketing ploy by other car manufacturers

There’s something like a 75% reduction in fatalities over the last 30 years despite there being more cars on the road (can’t recall the exact figures but something like that…).
But yeah, modern cars are rubbish
But ABS increases braking distance on snow, so I'm going to use that edge case to justify why we shouldn't have it!

Wasn’t the daf version just an early form of a cvt? I seem to recall it used rubber belts, so probably fine for a comparatively low powered car from that era but I guess even by the 70’s/80’s it was no longer much cop and better alternatives were available.
Cvt tend to sap quite a bit of power as well, anything you add between the motor and the wheels is going to reduce efficiency.
Regarding motor size, browsing specifications suggests that the drive train might be better at low speed, worse at high speed. Compare Nissan Leaf where 150HP rated motor gets it to 90mph, vs a random choice of Ford Fusion where 88HP gets it over 100. Fusion is lighter but boxier so i would have thought aerodynamics would be worse rather than better.

Probably optimised for intended use - there’s no point designing & gearing an ev for high speed when the range drops significantly with higher speed - and the speed limit is 70 or so anyway. (Bit higher in other countries but generally around there)
As said there’s no “gearbox” on an most ev, so you don’t get the choice to change up a gear (my hybrid car uses a small motor and the ice gearbox, I *think some ev have a 2 speed gearing arrangement, but I might have dreamed this!)
I agree. It is just as important for rear seat passengers to wear seatbelts. They would all have survived. My accident was actually worse than that one. When they hit the pillar the car spun around and travelled a bit further. In my case I nose dived into a concrete ditch. G forces were insane.
It would be nice to see this with a big modern car against a small modern car. Say a Range Rover against a Yaris. Both 5 star.

When they serve coffee and hot snacks it's pretty obvious people are going to spend time loitering.
They both have two parking bays, but they are before you get to the pumps.
The two near me that have been refurbished recently don't even have 'pay at pump' facilities, despite them being revamped during The Great Covid, when simply looking at someone for too long would spread infection, let alone walking past them.
If they had a couple of charging bays I could understand them serving refreshments, but forcing people to go in a shop to pay for their fuel, then surrounding them with temptations is obviously a financial move.

Of course a big car would likely come off better?
That’s simple physics. Im sure there are tests done to show this, but even if not then it stands to reason. All other things being equal a bigger crumple zone, more mass etc should make for a more survivable vehicle. But then cars are a compromise and not everyone wants, needs or can afford a large 4x4.It’s about doing the best with what you have. What is interesting is that a well designed small modern car is shown to be significantly improved over a larger but older vehicle.
