For the benefit of those not in the South-East, a 1.1 mile under-a-hill tunnel which makes the A3 bypass the bottleneck of Hindhead.
It fully opened last Saturday and I joined a PistonHeads crowd of about 30 cars there at 7 a.m. last Sunday.
My passenger didn’t show at 6:15 when I left home so I just strapped the camera to the passenger headrest and hoped for the best.
The video could be better (!) but I think the sound is good - loud!
