That seems so obvious I wonder why it hasn't been done before. I suppose those wipers costs a bit more since it must include some kind of conducts for liquid and multiple hoses(?).
More parts. Fluid needs travel through flexible and/or hinged parts. Longer hose. Cannot spray fluid without wipe (a big deal in cold weather). Fluid in hoses can be blocked (again, ice) whereas parts in engine compartment are kept warmer. No overspray beyond wiped area. No cross-coverage by multiple sprays in case one becomes blocked. Can the tesla sprays be aimed/adjusted by hand?
It's one of the many tesla features i just shake my head about. It sounds cool but there is good reason the other billion cars on the road went with the simple solutions. Water and wipers are cheap. Dont mess with a good thing.
Very old Volkswagen beetles used air pressure from the spare tyre instead of an electric washer fluid pump. I remember laughing so hard when I discovered that...
I was a teenager. Now that I'm an engineer, it's not so funny; it's an interesting design trade-off.
Because these windshield wipers get clogged all the time and most people at best just use water and windex which doesn't bode well for precision made spray nozzles.
They also tend to leave a mess at any point where you actually need to use the liquid e.g. when you are driving through sand/dirt or mud but then again most people won't drive their CLX through a swamp or a sandstorm.
Granted, you could be diluting the Windex, but it's already mostly water, and it doesn't have any freeze-proof guarantees to begin with, which wiper fluid does. I think you folks are doing this odd thing to entertain yourselves...
US prices in Europe and in the ME wiper fluid tends to be more expensive, but in all cases it's not the actual cost but the perceived cost (gas station/service center pricing rather than bigbox stores ala walmart) and laziness.
