I've noticed some of the "Waze shortcuts' making their way into Google maps. Some of these are pretty hairy. For anyone familiar with SF, here's an example:

To get from 8th & Bryant to 3rd & Bryant, Google Maps/Waze wants you to get on I-80 at 8th and exit at 4th. That would be OK but you enter 80 from the left side of the interstate and must exit within a quarter mile to the right side of the interstate. This means crossing 4 lanes to get there. It's actually do-able in bumper-to-bumper gridlock but when traffic is moving it's pretty dangerous. Why not just go down Bryant Street? The "shortcut" can't save more 2 minutes at best and at worst costs 10+ minutes.

Waze used to be good for spotting cops and speed traps. Now it's just a collection of bad "short cuts".
