Ok, so a guy I live with in my apt drives for Lyft. They just cut him off for driving because his vehicle (age) is past their limit. So now he has to go and find another one that is approved (age wise). How about some kind of grace period? Why not inform your drivers that their vehicles will expire in a few months? Personally, my concern is not about the age of the vehicle (within reason), but the reliability of the driver.
They probably expect their drivers to be aware of and follow their rules. https://help.lyft.com/hc/en-us/all/articles/115013077448-Vehicle-requirements https://help.lyft.com/hc/en-us/all/articles/115013078408-New-York-State-Driver-Information#vehicle
