As I say, choose your battlefield. I am not going to moralize with you about speed etc. I am commenting on your environment. This is not what I would call a great racetrack: Hard, solid trees close to road, blind driveway or street on the right. Blind crest of a hill. In contrast: This country has many places to drive. Some places are just better than others for fractional-Mach speeds. There are some places where the only person you would be involving is YOURSELF. PS: you can have more fun in less time and distance in a Hellcat than in most other cars. Vroom yeeha! Then slow down. Cars you have to wait a long time to pick up speed are more dangerous, in that one limited aspect. I did a speed show one night for a locomotive engineer along one lonely road at night. I trolled beside him, then hammered it, then slowed down. I did this a few times. It was fun. No animals were harmed in the making of this moment. I knew one guy who had The Red Corvette who used to get out on the checkerboard of Southwest roads and race the same train to multiple crossings, crossing well in front of him multiple times. As I said, choose your battlefield. There is so much fun to have that has almost no witnesses, spectators, or potential collateral damage. And make that woman wear her belts/harnesses, too.
LOL George Wallace was a famous s e g r e g a t i o n i s t running for president. I had to space the letters out because evidently some leftie crazy has his NAMbLA-protecting software set to erase the word "s e g r e g a t i o n i s t " as well as any other stuff of which they don't Approve. Actually, after Bill Cosby drove it, he returned it to Carroll Shelby because it scared him so much. Cosby's car also had twin superchargers. It sold for five million dollars. I suspect it would go for FAR more today.
On another note to further the safety angle: Hey, match your level of safety to your level of speed. Think of how cool you will be with a roll cage in your car, or even a partial cage. A parachute is a whole other level of cool! You can put a panic button on the hump to activate it rapidly. Just make sure you don't hit it accidentally! And always wear your seatbelt. If nothing else, it can help lock you into your seat if things get hairy, and enable you to steer, etc. instead of trying to hold your body from flopping around the cockpit.
To push this even further: "How would you design the car cage, belts, etc. and safety changes to your car if you KNEW you were going to be in a collision? BTW the Challenger was not really well-rated in front-quarter collision safety for the driver. Evidently it kind of crumples the footwell up pretty badly. You may want to consider this if you are designing any reinforcement additions to the car's chassis. A car in a collision has a finite amount of energy to absorb, and a finite amount of structural strength with which to do so. You don't have to make it like a bank vault. Just enough structural integrity to get you through a collision safely. It used to be safer in a front-end collision to get both your feet on the dash, driver or passenger, but now with the airbags being mounuted up there, it is not the case any longer. Chassis design looks different when it goes from a mindset of "What the heck, it ain't gonna happen" to "I'ma design this as if I'm going to roll right out of the shop and under the front end of a garbage truck."
