Thats a big difference from the practice tree to the real world, what light are you leaving on on both of them, most foot brakers leave on last yellow but if the practice tree isnt set up right you have to release on the green light. One thing ive found that help me on reaction time a lot was playing Guitar hero. You have to be dead on on the notes or you dont get the points. when i am the slower car i avg. probly .020 rt, if i am the faster car maybe .035. Most of my reaction times are less than .020 since I started playing gh.
