Seriously only downvotes?
Has no one driven a car with swapped wheels making the speed optimistic or pessimistic?
What about broken/missing temp sensors? Oil pressure gauges? Battery voltage?
The only thing you really need is a speed gauge, and you can get that from the wheels, the gearbox, and GPS. Making it easily three way redundant and have the ability to have a backup via your phone or manual gauge.
This looks like a good fun project, you could make it a HUD and keep all your old gauges.
For too many people, cars are beyond comprehension.
Most people can't even explain how a toaster works.
As Asimov said, it's like magic...its just not as advanced tech as one would think is required.
The increased safety in cars since the 90's is mostly to do with massively improved cabin strength (see growth in A and C pillars), and airbags. Crumple zones already existed and were constantly being improved. But you can't control the crumple if the cabin collapses.
I'm painfully aware of the lack of safety capability of my 80's car when I'm driving.
Even cars in the 90's were still mostly using the same tech as always, with modest improvements.
Speedo's didn't really start changing from cable until the 90's. Not that being super accurate is meaningful anyway - they never have been.
