How reliable would a CVT transmission be in constant stop and go driving?

someone said not to do any Ag comparision ,but I see by the retailers product pages and reviews that a lot of larger yard tractors and lawn mowers are going the cvt route ,I saw A very nice ,fairly new higher end John Deere sitting in the junk lot , at a sewage treatment plant ,Turns out the hydro stat drive unit went out and it was simply too expensive to repair it was cheaper to buy a new equall y as capable much cheaper red riding mower(they wouldnt let me have the twin briggsmotor ,I had a need for that) ever price a short block for a vertical 2 cyl Kawasaki,it will scare you to death.
All in all I think the CVT or even no transmission (electric vehicles) will come of age in autos.
