My personal battle with FSD.
Got the car with FSD just under a year ago.
Initial impression for highway driving, riding along on the highway, arm resting on the steering wheel is exactly the way to drive it… on the highway. It did a decent job there with little intervention and almost no nag. And it’s gotten better with updates. Just resting my hand on the wheel was fine for hours and it would navigate on autopilot and take the exits and change lanes to pass cars and whatnot. Didn’t always handle construction the way it should, but for the most part it was more than fine.
Initial impression for in town driving, it was useless. A gimmick. It did get better with updates, and perhaps my ability to anticipate the problems got better too. And by getting better, I’ve found myself trying to use it more and more around town. Having said that, simply resting my hand on the steering wheel DOES NOT WORK for in town driving! Are those of you that insist that resting your hand on the steering wheel actually trying to use FSD in non-highway situations? More on this:
Approaching an unprotected left:
OK, I’ve come to a stop and waiting on traffic clearing for the car to make the maneuver. Knowing that when it does, it’s going to be a quick spin of the wheel so I take my hand off in anticipation. While stopped, no nags, no problem. But as soon as the car starts spinning the wheel and moving forward, BLUE SCREEN! Wheel is still spinning, first left and then right. I end up taking control of the car, not because we are in danger, but because I want to avoid a strike and there’s no way to apply torque with the wheel spinning like that.
So then, I adopt the strategy of trying to keep a bit of torque on the wheel while waiting for the maneuver and try to anticipate when it will start the maneuver and let go of the wheel so it can spin left and then right. If I guess right, this works OK… I suck at guessing though. I mean, I don’t really mind if it takes an aggressive stance and punches through a narrow gap, or if it takes a patient ‘wait for the big gap’ approach. I just suck at guessing what it’s going to do. The result, it tries to rip the steering wheel through my hand resulting in an inadvertent disconnect and I have to take control.
So then, I adopt the strategy of just keeping my thump on the volume scroll wheel, rolling it back and forth while I wait to see how the car will handle the maneuver. But that leaves my hand in a spot that is less that appealing for taking over and is frankly a bit distracting itself when I really need to be focusing on several angles of traffic. I swear this was a factor in me almost getting T-boned a couple months ago. Tesla didn’t see all things, and neither did I because my attention was spit to too many directions.
This is just one example of how I find the nag to impede realistic day to to day use of FSD. Right turns at stop signs when the perpendicular traffic has no sign or signal is similar as is legal right turns on red as well as the plethora of construction scenarios or force merge traffic. Simply resting the hand on the steering wheel does not work HERE. “Resting the hand” works great on the highway, which would be fine if all I had was Enhanced Autopilot. But I don’t, I have FSD.
So when I first heard of this device, I got one (I see there are two referenced in this thread, I don’t remember which one I have). I can now use FSD in town. Am I paying attention? You betcha. And my hands are right there waiting to take control, if not actually on the wheel. I don’t trust the software enough to just let it do its thing… it still makes a lot of mistakes. But at least I can use it now.
I will say, I’m not a fan of threads like this that advertise it. If it gets popular enough, it will get shut down. It would be really easy for this ‘hack’ to get shut down. And it sounds like it did on the earlier versions of v12 (and because of this I would NOT recommend getting one for now). Some early reports indicating that maybe it works again with v12.3. We’ll see. If not, I’ll be doing my best to stay on v11 as long as I can.
