I was just wondering if this was legal to do on public roads? (ie not off-roading, just regular driving). I can't find anything looking in the HTA that says specific. There is mention of needing to have wipers on your windshield, there is also a mention of needing to have a mirror on your car - so if I have the doors off (thus side mirrors are gone) and then fold down the windshield (getting rid of the rear-view mirror), I would then not have a mirror at all.
I called the local police department and they said that it was most likely illegal but could not point to a specific part (didn't want to look) of the HTA.
