Quite a few years ago I had an idiot on the way home from work - had the Sunbeam at the time.
Pulled onto the main road then saw an old Astra hurtling towards me from the back, I emergency accelerated to 50 (in a 30 and he just managed to slow).
He followed right up my bum through the village until there was visibilty - then tried to overtake, however end of 30 so I booted it and lost him.
He nearly lost it on the next corner trying to get past me when I slowed for the corner.
Anyway all over me for the next half mile while the engine was warming and when I slowed, and I was not hanging about, then I said to the passenger "Shall we?" and he said "Yes".
Next bend is takeable at 70 in a Sunbeam, but not in an Astra

(I saw terminal understeer behind me), lost him on the straight, slowed down for a few bends and turn offs, the next tight bend I KNEW I could take at 60 in the dry and this was the last place I saw the Astra, again trying to get past when he had less grip than me and I knew the limits on that corner. I tucked in at 60 and he understeered onto the wrong side of the road at 50 or so.
After this my tyres were warm, engine warm, so I thrashed it and never saw the car again.
That driver was a total plank, you do not do 70 through a small village with blind junctions.
You do not try to pass an obvious faster, better handling car, which was being carefull past turnings and blind corners, and was pretty obvious was going to disappear into the distance once it got going.
At a later date that same corner also nearly took out a FWD hot hatch trying to follow me as I slowed down when a FWD wants to accelerate and it nearly went sideways, that was a good lesson in the different handlings of proper wheel drive and wrong wheel drive into tight fast corners.
BTW my Omega record for that corner is 50 (2.6) but I ran sticky tyres on the Sunbeam, the 2.0s rolled and didn't grip and the 2.6 tyres are not very sticky.
