You get a very different perspective as a pedestrian or walker. In the urban environment, drivers think they own the road and I would like to see more 20 limits and more pedestrianisation.
When walking/rambling (I hate the term ramblers), many drivers are quite happy to squeeze through at ridiculous speeds.
Once in Salcombe, an intolerant old fart in a Mercedes actually knocked my arm as he couldn't wait. His face said it all.
