Alongside the ‘avoid single track’ vote I also suggest there is a ‘stick to main roads’ option. Waze seems very keen to send me down twisty side roads where it’s hard to pass as there are cars parked on both sides, it sends me down country lanes which are NOT faster and through little villages, which, although scenic, can be very tiring on a long journey. Also, the side streets and single track lanes often lead to a tricky right turn (UK) onto a fast road, even a tricky left turn. I like Waze for the notifications of speed limits, but google navigation is superior, why can’t they combine systems?
