Ignoring that however, you cannot be bound by a EULA that you receive _after_ signing a contract. If you receive the eula before or with a contract, it may be valid
In any event it doesn't apply here. Because noone can tell who pressed accept.
edit: Also, if you open a new account as an existing customer that's because you've agreed to the terms previously and identified yourself by logging in.
I'm not saying you're wrong, but this explanation seems weird to me. If I get someone to accept instead of me, can I then abuse the software legally and they can't even (legally) revoke the license? That is very weird. What about Netflix accounts, is my girlfriend not bound by the ToS when I was the one who clicked Agree, and thus she could legally rip their content and share it? Very weird.
Just because the EULA isn't legally binding doesn't mean that the company in question can't act upon it. But you have no legal obligation to follow the EULA (because you didn't sign it).
When it comes to a "physical" license that makes it a bit more tricky, I'm not sure of the details. But they certainly can revoke the online-aspect of a product (tesla will (I believe) revoke super-charger access and mobile-app access if they feel that you violated their terms).
If you cheat in a multiplayer game that will probably violate the EULA (but not any laws). If you are caught you will likely be banned.

You both could legally rip their content (as long as you don't break any laws doing so (and by ripping and circumventing their encryption you most likely would break a few laws)). If they detect it they can and probably will terminate your account (even if what you did was legal). But you didn't break any laws by not following the EULA.
IANAL.
(Though I'll admit that that annoying screen was at least a partial inspiration for my original comment.)
Anyway, all the screen says, in essence, is that Nissan is using the aggregate data blah, blah, and if you want to use the nifty history telemetry, well, you're going to have to let the car send those data. Or not; car works just fine if you press "decline".
Of course, this data is yours, same with the car.
