Well, how many "if" scenarios do you want to imagine? Because you could come up with pretty much an endless number of them, and just the same for outcomes that would have been less catastrophic than what happened. Fortunately, these two guys are ok and ready to race again.
Actually, if both cars are built in US, steel tariffs won’t affect the price of one versus the other since both manufacturers will have to pay more for steel. But if one is made in US and the other isn’t, the price of the one made in US will go up due to higher price of steel. The price of the one made elsewhere will not go up. This is an example of how the tariffs hurt US companies that make things out of steel or aluminum.
