If the gate is open - yes.
If the gate is closed and unlocked - yes.
If the gate is closed and locked - no.

I would expect an access tag would be used if 'Joe' were not allowed or 
inhibited is some way e.g opening_hours, max_height.

Depends. In Australia the gate would be an extension of a fence line. 
Fence lines are where animals tend to run at speed and collide with 
vehicles.
Even if open I tend to slow, if there is plant cover obscuring the 
view10 mph or less, even then I have had a roo collide with the side of 
my vehicle. I stopped, it took off and failed to render details... hit 
and run.

If closed and fastened I have spent a good 10 minutes figuring out how 
to open then close the thing! Most are a minute, but ..
The more difficult one can be seen as an intelligence test, if you pass 
the test you can enter :)
