I was in the Hocking Hills area of Ohio on Tuesday, and decided to get a little footage of the area in my Type R. Apparently, some Honda Engineers had the same idea, as I passed a convoy of three cars clearly in testing. The first car was a 2020 Civic Si. The two remaining vehicles were camouflaged 2022 sedans with the telltale DRL signature exposed. I believe the two trail vehicles to be 2022 Si mules benchmarking off of the lead 2020 Si.
