It's a stupid annoyance, brought to you by the same rabid lawyers who brought you click-through software license agreements, email footers ("if you are not the intended recipient"), and warning labels on hair dryers not to use them in the bath.
But to me it's not quite as annoying as the press-to-agree screen on my Prius NAV screen, where you agree not to get so engrossed playing with the NAV that you forget to look where you're driving. It too has to be pressed every time you start the car, if you want to see a map. But the LEAF at least presents its annoyance screen right at the start. In the Prius it appears when you first select map or destination, so it's three clicks: map, agree, and map again.
Yes, I wish Nissan would fix it. But not as much as I wish someone would finally build some public L3, L2, and L1 charging stations. Nor as much as I wish the battery had 50-100% more capacity. Nor even as much as I wish the glovebox had 50-100% more capacity.
