Correct - you'll take the right hand "lane" at the Joe Mercer memorial, get to the main car park road and turn right to Alan Turing Way then north to Briscoe lane - and near the gasholders crossing all the cars trying to get out of Gate 1 where you used to come out. It's not clear whether any cars will be able to exit at Gate 2. If not, it will just create an extra conflict between vehicles and cars - but I assume that's the intention, as there are two lanes northbound and two lanes southbound at gate 2 but only two lanes northbound at gate 1 (and only northbound unless they take out a bit of the central reservation). And there are no lights at Gate 1 so presumably some men will stand on Alan Turing Way to stop the traffic (again, if not police, with no powers of enforcement).
It's an extra 300 metres to walk (in and out) - ten minutes extra at an average pace? For those who say this is a moan, I presume you've never walked along JMW in pouring rain.
They tried getting pedestrians and vehicles to share Gate 1 as an exit with a massive bottleneck for pedestrians at the pinch point. This will just make the pinchpoint at the Joe Mercer memorial, where people will be "crossing the streams" (from the west to the pedestrian lane and from the east to the car park lane). Who you gonna call? Traffic engineer busters. It won't work, even if people do what they're told.
I've always been sorry to miss the Mass Trespass at Kinder - maybe it's time for one at the Etihad.
