The 100 mph Motorbike Test

I've mentioned this before but perhaps I have a bigger audience. Rossett and Penyffordd are both
ex A roads or trunk roads now superceded by By Passes*. Penyffordd in Flintshire and Rossett in Wrexham.
A motorbike can ride through Penyffordd which is wide open and reach 100 mph before the end of the 30 mph limit.
A similar stunt in Rossett would make you brown bread dead. They have bumps and 20 mph Compulsory speed limit.
The mechanical method protects the village 24/7.
Proactive signs facing in the other direction do nothing.
Horses are ridden on this road by adults and children

* I am currently unaware of the true nature of Chester Road's designation
