So let’s ask this question. You constantly rant on here about how your semi is far superior to a pickup in all aspects of driving. Why do you even own a pickup. Shouldn’t you, by your claims, be driving a semi as a daily driver. Probably not. There are all kinds of reasons why that would be impractical. Also, the big rig semi oem’s have way more incentive to increase fuel mileage and the customer would gladly pay for better fuel economy because it affects their bottom line. The average consumer on a pickup wouldn’t pay a premium for fuel economy, as I’ve seen you argue in the diesel vs gas issue. You personally bought a gas instead of a diesel because the diesel, even tho it gets far better fuel economy, won’t pay for itself for a long time. There is a business decision that is being made here and on a consumer pickup, fuel economy isn’t as important for most as other features may be. You already have a option for better fuel economy in a diesel version of the same truck and as you know those sell about 30% to gas 70%.
Not saying that you are wrong about it being possible, just not practical. This isn’t a case of “if you build it they will come“.
