Yes, I already answered that before you specifically asked it here:Well I'd ask, why would Tesla sell the Semi at 1/3 the cost of the competitors?
So on the passenger vehicles they have no reason to offer low prices when they are doing so well in that market. In a different market of trucking, maybe they are willing to take a lesser profit margin to gain entry into that market segment. Maybe you're right that the semi prices are a bit of a loss at the beginning because they are expecting it to get better in the next few years, and they can support it with profits from the passenger vehicle market. Plenty of businesses do things like that.
