Also punch the guy that allows Google Maps navigation to flip back to a route that's been specifically rejected.

Earlier this week Google prompted me with "your route may be affected by tsunami warning". Indeed, so I chose the longer, inland route rather than the coast roads.

15 minutes later I realise it's rerouted me "due to traffic conditions" -- obviously the coast road isn't as busy!

(This has happened many times before, but this was the first time I had a safety reason not to take the faster route.)
