In any shop or dealer, could we put multiple items in a basket and when finished just go once to check out, instead of running with each individual item chosen, to the cash register?
Buy multiple cars, upgrades for all of them, and perform oil changes in all of them at once, without having to go back and forth through multiple menus, sounds great, got my vote.
Buying multiple cars at once would reduce the amount (in seconds or fractions of a second) of Brand visibility for the purchased car. I have argued in the past that this lessens the leverage that PD has when negotiating Brand licenses.....therefore they have not implemented.
