A properly designed “sports car” is way safer than an SUV, cause it will stop in much less distance and won’t run off of the road as easily.

tell that to the idiot that tried to pass my truck on the shoulder and ended up with both of my drive axles running over the front of his Porsche . ( no injuries thankfully. )

And if he had tried this in an SUV how would the result be different?
The SUV wouldn’t have gone under but rolled?
About the only real safety if you will for a passenger vehicle for really large vehicles like trucks and trains etc. is avoidance. Stopping and or going around a wreck as opposed to plowing into it.
Really doesn’t apply to boating though, so I’ll bow out

Tesla Lithium battery question.
Hydrogen due to its huge energy density is a realistic future fuel for cruising boats though, it’s likely the only way to make electric drive viable in a cruising boat, in my opinion.
It would also of course give you enormous electrical generation capacity, run anything you want, heat water, cook with electricity, run airconditioners, all silently from a fuel cell.
Using the linked video as a source, lb for lb it has 236 times as much energy than Li-P.O. batteries, which of course have higher energy densities than LFP.

This big difference between a boat and a car is that when the car catches fire, you simply step away to a safe distance. That's not an option in m,any cases on a boat, or create just another dire situation. So a different risk tolerance between cars and boats.

I got it, however if they have only 1/10 the risk factor of a gasoline powered vehicle, then it stands to reason that the fire issue is largely licked.
I’m still lead, will be for years to come I hope.
Hey, I’m the guy who still thinks Hydrogen is the future, I think the Japanese are right.
Electric is easier the infrastructure largely exists, there is no hydrogen infrastructure.

Can you post a link to those specs.? The only burnt Tesla I am aware of was burned by the fuel in the other vehicle.

Re: Tesla Lithium battery question.
A number of Tesla's have caught fire. IIRC the one that hung a fast left and crashed into a Jersey barrier for no apparent reason in the median caught fire. And 3-4 years ago, someone hit a piece of road debris which penetrated the aluminum battery shield and set a Tesla on fire. Tesla responded with a recall and replacing the part with a heavier sheet or armor, titanium IIRC.
This is not to say Telsa's or batteries are a fire problem. Every year in the US, two gasoline stations catch fire while people are fueling their cars--usually because they just HAD to step inside and buy some cigarettes and then come back out to light one while fueling.
But one reason that Tesla uses cylindrical batteries (18650 or the newer ones) is because there is a lesser risk of fire, partly because of the physical separation of the cells, partly because of the cooling system in between the cells.
VERY DIFFERENT FROM A BOAT.
Remember that thanks to people like Henry Ford, the Stanley Steamer got a reputation for exploding and being incredibly dangerous. Which was great for Ford sales, even if it was totally false.

Proven? Th only evidence that I've seen for that figure is a tweet by Elon Musk.

Let's do the math. There were 174,000 vehicle fires, causing 445 deaths in car crashes in the U.S. last year ( https://www.nfpa.org/News-and-Resea....-vehicle-fires). That's not a typo, 174,000! There are about 250M cars and trucks in use in the U.S. and just shy of 1M electric vehicles. That means electric cars make up 1/250=.4% of U.S. cars. That would mean if electric cars caught fire at the same rate as regular cars, we would have seen 174,000*.004=696 electric vehicle fires per year. Are we seeing 696 electric car fires a year? Every one of the handful has been breathlessly reported, nothing even close to 700. In fact, I'd say the 1/10 number probably doesn't do electric cars justice.
Proof enough to change your current opinion that was formed on the basis of ? Damn math and facts and stuff, I know.

Yes thanks.
Of course, there are other factors that possibly should be considered.
What happens if you only compare cars of similar age (how many of those 174,000 were old clunkers? )
I suspect that EVs on average do a lot less miles per year than the average petrol/diesel vehicle. How does it look per million miles driven rather than per vehicle.
But those questions aside, I'll accept that 1/10th as a ballpark figure.

Re: Tesla Lithium battery question.
How many of those car fires were not caused by the electrical system in the vehicle?
