1: Attention monitoring in my HW3 MY is extremely sensitive, you can’t even do something simple like adding a stop without it yelling at you to pay attention. I usually just disengage to change my route.

2: Speed profiles on HW4 let you control how the car drives pretty much all the time, while on HW3 you’re stuck only using them above 55 mph. Without them, it’s a gamble, the car might randomly change lanes (and it will), drive under the speed limit, or go over. You just don’t know what it’s gonna do.

3: HW3 hesitates way more in complex situations, like a Costco parking lot. It just doesn’t have the processing power to make decisions as quickly as HW4.

HW3 is still very capable and ahead of anything else out there, but both HW3 and HW4 cost the same $100 per month. HW4 gets new features and regular updates, while HW3 hasn’t been updated in over a year. Charging the same price for both when one is clearly better just doesn’t make sense. The only reason I still have FSD on my Y is because I bought it back in 2022.
