Hi everyone, DD and I are visiting relatives around the UK this summer and will be travelling from the North to East Anglia - a route I've done before - but then from East Anglia to North Devon. I last drove from London to Devon about 35 years ago. Since then, I haven't done much driving in that area at all. DD is a very nervous passenger, following a car accident a few years ago and I'm not great with motorways.
Our car will be packed full /heavy load and I tend to crawl at 60mph. I'm not sure which is the safest route to the south west - either M4/M5 (sounds like it's fast and a bit scary?) or the M3/303 - which is more scenic but slower and might be less safe if there are impatient drivers en route.
Is anyone familiar with this route in high summer? Which route would you recommend for me. Safety takes precedence above speed.
