but that's my question hybrid will need very little gas(at 45-50 miles/g) and 0 charging costs vrs whatever the cost is to charge a fully electric car
any other advantages a electric over hybrid?
In theory less maintenance for the electric car because fewer parts and systems. The hybrid has all the components of an ICE plus all the components of an electric. Another advantage is that the electric motor in an EV is designed to move the car in all conditions- and whereas with a hybrid your MPG savings depend on being able to drive in conditions that avoid using the gas engine, the car can't actually avoid using the gas engine in all conditions.
My experience with hybrids is that they fall short of MPG expectations in most conditions. Winter cold cuts mpg by 25%. Very hot weather cuts MPG by 10% or more. Short drives don't get much benefit from hybrid because the gas engine has to warm up every time. Any time you need to accelerate (e.g. light turns green) it uses the gas engine (unless you are willing to accelerate from 0-30mph in 25 seconds). A hybrid is a waste on drive up to the mountains. Real world MPG is probably the same as what you see on the window sticker if you drive like a stereotypical Prius driver AND have optimal weather + road conditions. Otherwise, you'll get less than you expect.
Bottom line to me is cost- if the hybrid is priced slightly higher than the ICE I'd take the hybrid, but I'm not willing to pay more than x% extra (x depends on which car, e.g. $2-3k extra for a camry hybrid vs regular). Electric is also cost dependent- right now the premium for electric is not worth it for the MPG improvement, but if we got back into a situation where all 3 types of cars were aligned on price I'd very strongly consider full EV.
