I've noticed gmaps has stopped providing optimal routes when navigating. Just yesterday I was driving to the airport and it showed me a very unusual route which it has never recommended before, the time to destination was 1h30min. It was strange because the usual route doesn't usually have traffic, so I decided to take the usual route instead. The time dropped to 1h10min. For the rest of the route it kept showing me unusual routes and I kept ignoring it taking the usual route instead. At one point it started showing time to destination at 1h50min. It took me 1h and I had to ignore the gmaps at least 5 times until there was no alternate route available.
