That looks like incredible fun. Your wife hit a home run with this gift.
A driving experience outfit at Las Vegas Speedway invited the press to do their driving experience and I got to do it. The cars were Indy car chassis and I think the engines were some variety of SBCs in some state of tune and they had 2 speed dual clutch transmissions. We had to follow a chase car around the track. We only got up to about 160mph but with the wind and bumpy track the cars were jumping sideways in the corners by what felt like 2 or 3 feet. It was intense.
The car I drove is the red one in the background. My chase car was the black one.
This is us on the track at about 150mph or so.
