can i sign up for a test drive before the line around the block inevitably starts forming?

Okay, but we can take this farther. Consider the following scenarios:

1. The inherent eroticism of the machine, etc. The mech gradually syncs up with you, enhances your abilities - perhaps even making you more than human, to ensure your performance is top notch. This may even include a hivemind aspect to it - after all, how can you act as one with your mech without being at least a little bit connected? This could even extend to team members, during piloting or just permanent. It helps with team coordination and all that. And it could have some.. interesting effects on your relationship dynamics to share headspace at least some of the time. Depending on how much of a machine you become, is another pilot getting you off masturbation or simple maintenance?
2. The mech transforms you to the will of the creators of the machine, potentially against your knowledge or consent. Possible brainwashing or dronification happens, to ensure you're an asset on and off the battlefield - including for private use. In a lot of AI learning, the robot is given 'rewards' for doing well and 'punishment' for doing poorly.. I wonder how you could translate that to a human's senses? Maybe a hit of dopamine or pleasure when you successfully complete a maneuver or follow an order without thinking? You might not even realize you're doing it, because as far as you're concerned, it just feels good.
3. The mech does in fact just transform you into a hot woman, or your perferred body. Why? Because as a mech, its job is to maximize your performance. If you're dysphoric or dissociating, this makes doing your job pretty difficult, depending - and the machine wants you to give a hundred percent, so transition it is. And what're the higher ups gonna say? Your battle tests are showing clear improvement as the changes progress. It also compensates for other issues to ensure maximum performance, but it just so happens that the biggest problem is your dysphoria. You shoot up to being a top performer and no one is allowed to complain.
