| Vehicle Speed Control problems |
Speed profiles don't adhere to actual speed limits. Speed can be higher or lower than posted. I can be driving in a 55mph speed zone and it will drop to 35 then accelerate to 65. On roads that have no speed limit posted car tends to want to go 55 rather than a more sensible speed of under 30, especially at night on a dirt road with wildlife about. Car will also see access road speed signs and slow down in the middle of traffic. To me I don't feel safe and have to disengage the system which adds stress to the drive. Being able to set my own speed is the solution, not having the car set it.
Supervised fsd does not have a remedy if it assigns an incorrect speed limit to the current roadway. The only action available is to disengage fsd. This incorrect speed limit happens quite often, especially in construction zones with temporary speed limit changes. Tesla used to have a ‘max speed’ setting that the driver could use to override an incorrect speed limit, but they removed that capability.
