At least until later today.
9:40 last night; driving on a 6-lane street approaching a red light where I need to turn right; no cars in my lane so I can make a right turn on red; little sports car speeds by and gets in my lane ahead of me so he can be first off the block when the light turns green; I turn on my right turn signal; he notices and immediately changes back into the middle lane so I won't have to wait; I pass him and wave a "thank you"; he changes lanes again and gets behind me; I make my right turn on red; the light turns green for him and he is indeed the first one off the block.
Though probably young and obviously in a hurry to get nowhere fast, he was also considerate.
And this happened in Dallas??
