And get your information about dangers from there, too? Restricted turns? Watch the signs! Traffic jams? Keep a look ahead! ...seriously?
I could do my daily commute completely without the assistance of waze. But it's meant to maker things easier for you. I never drove myself in the US, so I'm not sure what it looks like over there. Here in Europe we have roads where speed limits vary a lot. Outside of cities Germany has a general speed limit of 100km/h (~60mph). But these streets could also be limited to any lower value. Furthermore streets with two lanes per direction or where lanes have constructional separations, the limit is 130km/h (~80mph). In cities the general limit is 50km/h (~30mph) except for multilane roads or seprated lanes where it can be up to 70km/h (~45mph). On highways there's no general limit. However there are many sections which are limited. We also have dynamic limits, which are set automatically or manually when traffic increases, or visibility decreases. Sometimes with individual limits for each lane. On 10 miles of highway the speed limit may vary from 60km/h (~40mph) (road construction) to "whatever your car can do". But few hours later the maximum limit could be only boring 120km/h (~75mph).
If waze offered a feature to inform you about the current speed limit, I'm convinced that over here many wazer would use this feature. I definitely would!
Everyone knows, that waze doesn't offer any official information. When you drive too fast because waze told you so and you get caught, it's still your own fault, just like it's your own fault when you take a disallowed turn or go the wrong way in a oneway street. Waze is an assistant, not an autopilot or a controller you must obey in any situation. I guess this is clear to all of us.
