I keep hearing this, and don't understand it.
If we pretend that the trunk/hatch decision is based ONLY on making the most people happy - is there really any argument? (removing cost/safety from the discussion for a moment) Is there anybody who wants LESS utility in their car?
But what would be the point? Every design is about compromises and balances. We want the biggest space, the largest opening, the lightest material, the strongest structure, the stiffest chassis, the cheapest building cost, the longest range, the highest capacity batteries, the fastest charge time, the quickest acceleration, the safest cabin.... I am sure Tesla engineers would want that too. But they have to make choices, and I am sure they did not arrive at the decision easily or without careful considerations of various design options.
