We need to take a car full of stuff to a relative about three hours drive away across five motorways at some point over the next three days - going there and back in a day. Starting point is inner London, and we'll be going past Heathrow.
Does anyone have any idea how bad the roads are likely to be on Friday and Saturday? I guess they'll have more traffic from people returning from holiday cottages as well because they're changeover days, but the return into London on Sunday afternoon past Heathrow airport might be a bit nasty too.
