If you drive carefully at 20mph, keep in high gear low revs (e,g, move of in second gear and do not spin drive wheels) and have reasonable tyres. a light foot etc etc some back streets seem quite empty - I'm just guiding a friend (from Loughhborough junction to Nunhead) - up Herne Hill Road, right into Ferndene, left down Denmark Hill and right up Champoin Hill, across Dog Kennel Hill. down Grove Hill, left and right into Malf Road, Avondale and Maxted to up Crystal Palace Road, left into Underhill left on Dunstans, up Colyton / Homestall (oops - some silly b----er driving fast has just hit a parked car!!) and home Hope that helps someone - if you have any grip at all try it as the roads leading to all the hills e.g. Forest Hill Road seem blocked by stuck cars
