At least in Europe, there are a few big reasons. First and foremost combustion engines are more profitable. EV require a lot of R&D and factory investment, which is not needed for old school combustion engines. The other part is a shrinking car market. Covid means a lot more work from home and at least in Europe, you generally have the option of doing a lot of things on foot, bicycle or public transport. At the same time, when you drive less you do not go for a new car as quickly. Then you have cost. Due to supply chain issues battery prices have not fallen quickly enough. There was a bit of time, when they were stable. Good news is that they are falling again.

In other words, this is a difficult transition and some car makers are going to fail.
