I'm only talking about passengers cars. I think Hydrogen could be viable for long haul as it may be better at towing.

Model 3 and Mirai have similar interior space (Mirai is smaller) as well as price. 2021 Mirai is a giant car on the outside because a hydrogen car has horrible packaging due to all the components.

There are pros and cons to both.
According to EPA, the interior of the 3 is has 3 additional feet inside that the model S...exterior size is still relevant as well.

But missing tons of features and amenities for a car of that price.....and then there are the quality concerns as well. I don’t think anyone will cross shop a Tesla 3 either.
Anyways...this has turned into the typical Tesla BEV vs FCEV....neither is supposed to win and Toyota will be bringing battery electric vehicles to markets....it will also offer FCEV in places that will support them, There are benefits and limitations to both technologies

Hence Model S and A7 have only 94 and 95 cu ft passenger volume respectively, however their liftback trunks are 26 and 25 cu ft respectively; both liftbacks are square overall...

Powerpaste could solve hydrogen's storage and delivery problems
It's 10 times more energy dense than today's batteries
Hydrogen holds tremendous potential as a clean energy source, but there are still significant hurdles to overcome before it becomes a legitimate option for cars and trucks. Two of those issues are storage and transportation of the fuel, particularly when large high-pressure tanks aren't an option. A new creation called Powerpaste, developed by a research team at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials in Dresden, Germany, could potentially answer those questions.
According to the Institute, Powerpaste is made up of magnesium hydride (created when magnesium powder is combined with hydrogen), an ester and a metal salt. A plunger pushes the paste out of its container, water is added and hydrogen is released. Half of the hydrogen is released from the magnesium hydride and the other half comes from the water. The resulting hydrogen can then be used to generate electricity using a fuel cell.
Because both parts of the mixture release hydrogen, the combination of Powerpaste and water can reportedly store more hydrogen than standard high-pressure tanks and is 10-times more dense than today's batteries. And since both the paste and the required water are easy to carry in cartridges or canisters and don't pose a dangerous threat in high temperatures, no significant infrastructure is needed to make the fuel source available to potential customers.
The Fraunhofer Institute suggests that electric scooters and motorcycles are an ideal initial test for its Powerpaste, and it plans to launch a production plant this year to produce up to four tons of the fuel per year. If that's successful and everything works out as well as they hope, the researchers hint that Powerpaste could be useful for other sectors, presumably including automobiles.
Of course, hydrogen has other hurdles to overcome, chief among them revolving around a good way to capture hydrogen in the first place, but we're certain researchers are working to resolve those questions, too.

10 times more dense than batteries. The batteries in a Tesla weigh what 1000 lbs? So 100 lbs of this goop gives the same range and when depleted just replace with another can of goop. It’s interesting indeed.
They don’t however mention the cost to produce. Hydrogen production is expensive. Very expensive. Currently not cost effective for vehicle use. Maybe this paste will be.
