How does a GPS work with ETA?

851 views

I noticed this the other day, I turned my Google Maps GPS on, put in destination. It told me the trip would take 9 hours. I drove ~8-10 over the speed limit, hit almost no traffic, it took a bit under 9 hours.

How does it calculate time? I would have thought going 8 over the limit for 9 hours would have meant I would have gotten back over an hour earlier, no?

Apps like Waze and Google Maps (who bought Waze a few years back) use crowd sourced traffic data. What this means is that it takes the average speed data of everyone that is travelling on that road and using their app. If the average user is speeding, then that is the data it is using to calculate the time it will take.
