Tesla’s a Game Changer When It Comes to Windshield Wipers

I wouldn't say 'game changer', but it's different.

Looks like the wiper arm/blade stand up all the time at the edge of the glass when not in use. It'll take a lot of punishment.

"... the only friction in Tesla's wiper system is from the guide rails on which the arm slides."
Seems like that ignores the friction of the blade on the windshield itself.

As for reliability, I bet most otherwise used-up cars still have operational windshield wipers.

Build the car with magnetic bearings and bushings, and it will last almost forever.

This design is all about doing it effectively with less power. There's never been a reason to move away from the current system, because there's always been a powerful generator built into the car.

A little googling around says that a wiper motor, running full out, draws 10-12 amps of 12v power. That's a lot of electrons. So I bet Tesla is actually saying, hey... if we make a wiper system that draws a lot less power, that will save 20 miles worth of range in the rain.

It's a good reminder that everything is a trade off in their cars, pushing the envelope hoping you don't become stationary. Someday battery tech, or capacitors, will make that all a memory, but not yet.

That '57 or so Scaglietti bodied 250 TR is my favorite car of all time. I watched them race at Riverside, Laguna Seca and Pomona.
The names Ginther, Hill and Gendebien (sp?) all come to mind.
There were slight variations that I like better than this one, but no matter.
250, BTW, is the displacement of each cylinder.

Poking around the subject, I came across this vid of a different Ferrari. There is something really strange at the end.

I didn't see anything particularly strange. The IRS makes the wheel look a little odd when it goes over the speed bump, but that's about it.

I don't get it.

Couldn't see the driver.

Flat tire... probably, where ever it is.

Then how are we or you gonna recognize someone by the white rectangle covering their very identity?

Why would you even ask?

This is how I come to hate so many people.

If you start over with my first post and think it over, maybe we can avoid another meltdown.
