I think hydrogen fuel cell cars are the future. Batteries are by accident, planned obsolence. You have to buy a new car every 5 years due to batteries losing their charge over time.
There is a common misconception that EV batteries die within five years, forcing owners to buy a new car. However, this is not the case.
Battery technology has improved significantly, and new types of batteries, such as Li-S batteries and lithium titanate batteries, have the potential to last the life of the car or even outlast it[1].
Many EV manufacturers offer warranties for their batteries, typically ranging from 8 to 10 years or more, indicating that the batteries are expected to last for a significant portion of the vehicle's life[1].
With proper care and maintenance, EV batteries can last for a considerable amount of time, and ongoing research and development efforts aim to further improve battery performance and longevity.

Show me any car using Li-S or Lithium Titanate batteries that is sold and on the roads today.
Have you even bothered to do the most basic Google search before posting this BS?
Hydrogen is interesting for remote use cases, but the 10-15 year old used Leaf and Volt market argue against your second point. Most battery issues will be discovered in the first few years and after that it's minimal (1-10%) loss after a decade, using far older tech than today's models. The industry does need some standardization on battery modules to ensure less e-waste, more mechanics, and better pricing.
Tesla's battery warranty is 8 years and between 100-150K miles. I'm not sure about other manufacturers.
And where would the hydrogen come from?
The two most common schemes are either producing it from natural gas, or wasting electricity to produce hydrogen via electrolysis.
Either way, hydrogen is a waste of resources for most applications.
