Pen that’s safe to keep in the car?

Seriously? It's just a car.
Not the car my friend...the other stuff in the tray that gets covered in ink. I’ve had pens leak twice in hot cars and make a huge mess of all the stuff in the tray. If somebody who’s been through this had a recommendation, it’s worth asking. The Fisher space pen was a helpful idea though, so thanks to @MorrisonHiker !
Had to go to Tempe, AZ in July for work. While renting a car at Hertz, they made us sign an agreement, that if we left an ink pen in the car and it exploded, we were responsible for all charges required to clean the car. According to Hertz, it happens more often than people think, due to the extreme summer heat. I just remember it was so hot I couldn't even touch the door handle on the outside and the steering wheel on the inside. The business I was at didn't have any trees, only cactus, which didn't provide any shade......
I've never had a pen explode in a car. If you are worried about it, you might consider a Fisher Space Pen: Fisher Space Pen Co.

The work in zero-g, upside-down, in extreme temperatures, under water, in grease, etc.

Another option might be to use a mechanical pencil.
I keep a space pen in the car myself, and I live in Florida. Never had a problem.

is this like the the old joke about how much money nasa spent working on a pen that would work in space.......and USSR just used a pencil.
You know that's just a joke? American astronauts and Russian cosmonauts used pencils for a period, but graphite is electrically conductive and broken pencil tips are a major hazard for electronics in space. Plus pencils are flammable! In reality, NASA did not pay for the development of the "space pen". They only paid to purchase pens in bulk, paying $2.89 a pen, the same price the Russians paid for the same pen.

Maybe an unusual question. I like to keep a pen in the car, but there’s always a risk that on a hot day it will spew ink in the console tray. Do you have a recommendation of a car-durable pen?
You can get one of the compartmentalized organizer trays for the center console, and keep all your bombs pens in one subtray.
