Safety is of course a serious issue. However the current demand for EV high profit fun to drive products is pretty clear. So addressing the margin issue with higher priced batteries is actually possible. The same logic applies to use cases where the cost to own is significantly cheaper than gas. So applications like 50,000 mile a year Uber or police driving, delivery vans and semi trucks. These use cases account for (just guessing) about 25% of light vehicles, 80% of semi trucks. My guess is these segments will consume all of the production coming on line for several years. If so the consumption of gas and diesel will likely decline by 50% within 8 years.
What will the oil industry do if they predict EV growth will lower demand and is not highly driven by fuel cost? Note EV advantages in maintenance and vehicle life are major factors, fuel cost saving only about 30%. Knowing EV production ramp limitation the oil industry likely will increase prices and lower costs, fewer gas stations less drilling…So EV demand will be sold out for years and oil prices are not likely to be lowered to slow the shift. Of fact the oil industry steps will cement EV demand.

In the meantime how to address more price sensitive markets? Current EV have batteries sized to high performance 0 to 60 acceleration. A lower priced EV with acceleration equal to say a Honda Civic can be made today with lower cost drive train and battery.
What I am basically saying is production growth is the major limitation to EV growth.
Having said that, grid batteries might be more limited by current battery life cycle cost.

No doubt investments in new battery technology will continue, the issues you noted continue but I would add production ramp as well.
