Had my first experience of the 20 today. Magor to Portskewett.

I stuck to 20 in all the 20 spots which is about 75% of the five mile journey. I had three cars overtake me and one w4nker sign off a brand new 22 plate Range Rover driver

On the return journey I had two vans overtake me but no w4nker signs

My truck struggled to stay at 20 and my fuel average was 4.6mpg. I later did a 4 mile stretch of road and stuck to the 30mph limit. I averaged 7.7.

I'll be honest, I found it an absolute ball ache.
