I miss my '73 Honda. Four "dash" indicator lights - two of which were malfunctioning. Turn signals didn't blink, so I used the hand signals that nobody else seemed to remember from driver's ed. A speedo and a tach that also could never operate at the same time (and also didn't have Km/H). Finally, if there wasn't oil under it, then I needed to check there was still any in it. My worst habit was likely when passing and a tendency to cut back in closer than another car would. I'd still be accelerating at that point though. So while not particularly dangerous, it probably unnerved more than a few other drivers.
