Well the model 3 does not work like that. The way it works is you press the stalk for a single wipe or continuous, and then if you like, you can easily press a manual selection. That's how the car works.
It may have changed, but AFAIK, there's no way to activate continuous wiper mode via the stalk, at least not in the Model 3 (this is the Model 3 forum); the stalk button will activate either a
single wipe or a series of a few wipes in conjunction with a spray of wiper fluid. From Tesla's manual:
Tesla Model 3 Manual said:
To perform a single wipe with the windshield wipers, press and immediately release the button on the end of the left-hand steering column lever.
Tesla Model 3 Manual said:
Fully press and hold the button on the end of the left-hand steering column lever to spray washer fluid onto the windshield. While spraying the windshield, the wipers turn on. After releasing the button, the wipers perform two additional wipes, then a third wipe a few seconds later.
Part of the debate in this thread is about your "easily" claim. Pushing a button on a touch screen is fairly easy if you're sitting at a desk, on a couch, etc. If you're in a moving car, especially on a rough road, it's harder, because the car's irregular motion makes it harder to precisely touch a small area of the touch screen. If you're driving the car, it becomes harder still, because you've got to take your eyes off the road, locate the correct part of the screen, and touch it, all in as little time as possible. This takes time, during which time you're
not looking at the road, which reduces safety.
Still don't see the big deal. Single wipe until it's safe to pull over and then do whatever you want.
That's fine if it's drizzling, but in a downpour it's
not safe! Two or three times a year, I get caught in a situation in which there's either no rain or it starts light but then ramps up suddenly to much greater amounts of rain. In such conditions, there is no "until it's safe to pull over," because it's not safe to keep driving
then, at least not without turning up the wiper speed. It's likely safer to use the Tesla's on-screen controls for this than to try to find a place to pull over, but it would be safer still to have controls on a steering wheel stalk to enable the driver to do it by feel. What's more, there are conditions when the level of rain increases and decreases frequently. That's what the Auto setting is supposed to handle, but in my experience, it does a middling job of that at best; so if you use fixed-interval wipers, you've got to be either adjusting them frequently or setting them ridiculously high even in modest rain. Advising drivers to pull over every two miles to adjust the wipers is ridiculous. Adding a $1 switch to the steering wheel stalk, or as Zooner suggests, programming a scroll wheel to pick up the slack for a few seconds after pushing the wiper-activation button, is a much better solution.
I encountered this problem for the first time in my Tesla on a road trip about a month ago. (I've owned the car for three months.) I used the on-screen controls to increase the wiper speed to maximum, since Auto wasn't running the wipers fast enough, but I wished that I could have done it by feel, the way I'd have done it in any other car I've driven.
A deer jumping out while it's raining really hard is a rare occurrence to 98% of drivers.
Sure. So is encountering a truck that skids and flips just in front of you. Tesla brags that its cars are engineered for safety, and that means protecting its occupants in the event of rare occurrences, whether that's a truck that skids and flips or a deer jumping in front of the car. Tesla's crashworthiness might well help in the event of colliding with a deer, but if better wiper controls let you avoid the deer in the first place, that's better still.
