there's also one other feature, which is worth mentioning. it's very easy to set new tracks using the device. you just have to drive the same route three times and that could be anywhere, including public roads. now, the device discourages this through an on—screen warning set—up, and garmin told the bbc that it doesn't encourage any form of illegal activity. but what is interesting is that the device's design team haven't used geo fencing to restrict its use to race tracks. back on track, we wanted to see what it was like with a pro, so we sent in 2017 british gt winner seb morris around for a spin. he laughs. when we think of cars of the future, we think autonomous self—driving machines. just told me to aim later.
