I have just installed the R1 and will be using it on track for the first time next week. The decision to buy this radar unit arose from an on track incident that happened in May. 2026, where another car attempted to pass me on the same racing line. I did not see the car approaching and I think having the R1 may have well prevented the damage to my Radical track car. Fortunately no one was injured..
