True, but only about 40% more depending on battery chemistry. The amount emitted by a typical ICE car during its lifetime can be 3-4x its production emissions. Depending on what type of power is used for charging and how often/long it's used an EV can easily come out ahead.
> what pollutes the most in onroad vehicles are car tires not exhausts.
Also true, and EVs do typically pollute a fifth more in large particles iirc, which is terrible for people's health but in climate change terms has no impact on the greenhouse effect. Smaller batteries and more accesible fast charging would entirely negate this problem, but alas the networks are still in their infancy. If there's no mass adoption there's also no reason to cater to that sector.
> their electricity comes from power plants, which are predominantly not renewable
Heavily depends on geography (e.g. as an extreme example in Norway it's 90% hydro), and that's a problem that has to be solved for grid carbon neutrality anyway.
There's more to having an EV than just driving too, lots of people have been pioneering their use as home battery storage for their roof solar, which should reduce load on grid coal and gas.
