用FSD并像normal driving时100%时间专注 不可能也没意义

Need to distinguish routine/boring driving on the same high way.

我会专注 when a lot of traffic is merging onto the lane you are driving. In normal driving, I would avoid staying in that lane by increasing speed or slowing down to avoid that lane or getting too close to pack of merging car unless I have no other options. FSD does not do that well yet.  

我会专注 when there is lane reduction; when there is construction on the high way; going to one high way to another. 

我在Dallas开朋友的Tesla 去/来机场的路 many times, 人轻松很多

 1） turn left at a flashing yellow light at a busy st ( a few lanes each way). Did not get chance to complete left turn and Tesla started to go backward when yellow light turns red. It was probably safe but I took over. 

2) Need to exist one high way to another highway. probably a split second delay at around 40-50mph

3) Tesla was planning to exit a high way when another car speeded up so tesla missed that exit. I did not know the direction so I let the car drive around by itself.
