Come up against a Red one on the A470 near Merthyr today.
I think it was a 340MR.
Was two people in the EVO and just me in the Soop.
He joined at a roundabout and I thought he may go for it. I joined the RB after him and moved into the fast lane the other side of the RB.
I saw some black smoke out of his exhaust just as I put my foot down to pass him.
Anyways, manage to pass him and start gaining speed. Got up to 140 leptons before having to brake for cars in front. However from my glances in the mirror he seemed to be stuck on my ass.
Now I know I cant judge the distances behind that well, as the misses in the megane I dont think looses ground as fast as i'd like, but when we get home the misses said I flew away from her.
All in all, not sure about it but it was defo looking like he was keeping with me.
Very shocked really especially when there were two people in the EVO and just me in mine.
