Just drove down the I70 from Dillon to Denver in Colorado. The I70 has horrible ruts in the road surface (made by heavy trucks) - comming down from the Eisenhower tunnel form aprox 40 miles. Right now FSD 10.9 positions the car right in the middle of these ruts. There needs to be some way to offset the cars position in the lane to avoid situations like this - and also detect & avoid nasty potholes. Right now FSD is not usable as is on road conditions like this.
