Since the Guest account obviously has access to the Admin account's home directory somehow, this does expose a deeper security flaw.

It's not *access* to the admin user directory. Perhaps the cause is that there is a bit setting somewhere that is marked when a guest logs in that says "Erase my Home DIrectory". If the bug happens only after a hard reboot back into the admin account, the system likely mistakes the setting as having been applied to the "current" account, and the setting persists the hard reboot (like in PRAM or something). This does not indicate that a guest has any access to anything he/she shouldn't.

After all, they cannot teach their students that which they themselves do not know.

You don't work in K-12, do you?

Yes, but count tonnage per passenger and I think you'll find the cars are a lot worse for efficiency, so the accelerating and stopping per passenger is a lot worse for the personal vehicles.

So, we should look for something that weighs about as much as a bicycle?

These are convenient only for places they go, as well.

So, we should look for something as nimble as a pedestrian?

the only thing they have going for them is being electric instead of fuel

The only thing better would be if it used some energy source that was already in use all around, maybe it could even tap into the extra calories Americans consume everyday and help us keep healthy? And, as long as we're dreaming, it should cost $0.00 for infrastructure. Damn, if only such a solution was realistic. Anyway, I gotta go, I've been looking forward to my bike ride home all day. Maybe on my way I can try to solve this dilemma.
