   The speed recognition of Tesla Full Self Drive is unsafe in its present form. The speed recognition is very inaccurate. While driving on an interstate highway where the speed limit is 70MPH, it is recognizing a route sign with a much lower number as a speed limit sign and suddenly applying braking, causing me to nearly be rear ended on multiple occasions. Every time I pass this sign I have to either disengage full self drive, or I have to override it to keep from being rear…

   Tesla took off from a parking lot and was uncontrollable, went through the grass, crossed the street and construction before hitting the barricades and fell into a sewer as the road ended there. There were 2 passengers in the car and luckily both passengers came unharmed. But FSD needs to be investigated on why this happened.

   Tesla's FSD system has ZERO opportunity for the driver to adjust what the car believes is the speed limit. My car often has no idea what the speed limit is. More often than not, it believes the speed limit is lower than it actually is, by as much as 30 MPH. This causes the car to impede traffic if I do not intervene. I can press and hold the accelerator to force the car to drive the speed limit, however I am then faced with a warning that the car will not automatically brake…
