Did you give him a 1star rating?. That's is the best way to weed them out.
IIRC their star rating is the average the last 500 ratings.
Drivers don't want to get less than a 4.8 rating because then they become non preferred below 4.8 and don't get as much jobs.
Lets say in last 500 rides there is
400 rides = 5 star
100 rides = 4 star
Avg = ((400×5)+(100×4))÷500= 4.8
Now lets say you give him 1 star. So the last 500 rides become (with the oldest ride dropping off - say it was a 5 star):
399 rides = 5 star
100 rides = 4 star
1 ride = 1 star
Avg = ((399×5)+(100×4))÷500= 4.79
A few points to make in the scenario above
1)The oldest of the 500 rides drop off first and so the the most recent 1 star ride stays for 500 rides before it drops off.
2) If a 5 star drops off and is replaced with another 5 star, the rating average will remain at 4.79.
3)The only way to get back above 4.8 is to drop off a 4 star and replace with a 5 star. When that happens will depend on when a 4 star actually drops off and is replaced with a 5 star.
4)And he needs 4 rides of 5 star to replace 4 rides of 4 star to get up to 4.8. But that may take a while depending where the 4 stars are in the list of 500
The other point to make is:
If a driver with an average rating of 4.0 is likely to be deactivated. If people give 4 stars for a "normal" ride, drivers will be hovering around a 4 average. So the normal cannot be a 4 star. A Normal rating should be a 5 star.
