Serious question:
Take a downhill ski race course and duplicate it on level ground. (paved)
Turns should be identical.
Would a ski racer and a race driver follow identical lines on respective tracks for best results?
They are not racing each other, but just trying to achieve best results on their own.

They would be very different. Not just "power" but terrain, snow condition, speed of entry and many other factors are different.
There are similarities (going slower at turn entry to maximize speed on exit) and similar apex's but its still quite different.
Source: Ski raced competitively for 12 years.
Product recommendation request:
I'm in need of a car battery charger. But I would also like a jump box.
Suggestions? Preferably compact and easy to move around. Not battery powered, but wall outlet powered. ~$100 or less
Current first choice:

I have a 15A B&D "Vector" charger. Alas, I don't think they make them any more.
For jump box, I have an Anker lithium ion pack that I'm quite pleased with.

I want them in one box. I don't need another battery powered thing that will be dead when I need it. And will die slowly over the next few years.
I want something to plug in and go.

car must have 9.8 m/s2 constant acceleration
top speed limited to 160 kph
no brakes
rock hard tires, prone to sliding

A downhill skier does not accelerate at 1 G. Their acceleration would be a function of G, the angle of the slope and wind resistance + friction.
It's not freefall in a vacuum.
And acceleration is not constant.
There are many tracks with tight turns and short straights where a car would not be able to exceed 100 mph, so that is not a deal breaker.
Besides, I was asking about whether or not a car and a skier would follow identical lines through identical turns.
Speeds could be different, but that does not mean lines should be.
You'd be surprised how much braking skis are capable of.
I'd be willing to bet a skilled skier would be able to outbreak a lot of cars at sane speeds.
Skis also turn quicker than a car.
And, a pair of downhill skis are nothing like rock hard tires.
You can generate pretty impressive lateral G forces on a decent pair of skis.
Yes, you can slide if you like, and that really bleeds off speed in a hurry.
If your boots are cant-adjustable, or if you have perfect stance (I do) you can maintain a lot of speed when you need to.

I was watching men's downhill races and started paying attention to all the different lines the racers were using.
That got me thinking.
Inevitably, those who turn in early and get an early apex are faster overall.
