Musk said that the Tesla Semi while always better than diesel trucks on economics will also beat rail in platoon mode. 1. Average locomotive range is 500 miles. 2. Semis are apparently responsible for 80% of freight haul in the US. Taken together you see that Tesla Semis match the range of rail- eliminating any range concern, while matching the flexibility of a truck but of course also beating diesel trucks on cost. Let me also add that mandated 30 min break matches range limit for Tesla semi and the recharge rate is in the range of refuel for a diesel. With Musk noting that energy will be locked in at 7 cents a kwh because solar charges power paks at each charger station or "mega chargers" and spread across the super charger stations. This reminds me of one of petrol's stupid canards: that cheap gas and diesel... have an impact on the adoption rate of electrics. They do not at all. Its a way of trying to say the helpless petrol industry has some power over its utter now totally obvious now long time obsolesence. It does not. Petrol rates are unreliable they raise them to protect the rich from deflation and enrich petrol rent seekers in the process at our expense. Nothing can stop this now petrol is the black berry against the iphone but in this case its an iphone that doesnt need a telco or ISP and we learned that all the Telcos stole tons of money from us.
