I'm really glad they don't. I wasn't big on the whole e-CVT thing when I bought my Prius, or CVTs in general, but making fake shift points would ruin it even more. Their flexibility is the whole point; looking at the Scangauge, engine RPM is constantly fluctuating even on steady-state highway drives.

This is why automakers have started making CVTs imitate geared transmissions. People are used to hearing RPMs rise and fail as the car shifts through gears. When the CVT jumps to peak torque and holds there it sound funny to them and it sounds like they are revving the engine to death.

I had a 2019 Nissan Altima as a rental last month. 2.5L DI with a CVT that imitates as gearbox. It returned 41.5 mpg. Not bad for a car with less than 10 miles on the odometer and considering I climbed over a mountain range twice.

CVTs paired with a torque converter, makes for one great experience in start-stop traffic.

If your car is dog slow with a CVT, it will be even slower with a manual transmission; as usually the CVT tries to hit Torque or HP peak power when accelerating (accelerating at a constant peak of the engine's output).
