is ben here out of a job? so far, my best time around the track was a 151.6. i was getting faster, but could the catalyst make a difference? now, when you're driving a car around a track, you're aiming to do one thing — take corners really well. it's all about timing, braking in the right place and trying to keep the car on the fastest line. to help with this, the catalyst uses a camera footage to the dashboard, along with gps and accelerometers, to work out where you are on the circuit. after three set—up laps, it analyses where it thinks improvements can be made and then coaches you in real time as you continued round the circuit. brake hard.
