That means you roughly need a 220lbs charge cable if it's 10ft long.
That is not something a person can handle anymore.

There is of course an alternative, called hydrogen.
This is the point I try to make all the time on this subject. While battery tech may slowly increase energy density, the cost will increase and the charging infrastructure cost will increase along with the need for specialized training of charging personnel. The are limits of physics and chemistry that will limit charge density and cost per kilowatt.
