I use mine quite a lot - in good weather for parking rather than leave it open or putting the hood up.
If sidescreens on I tuck it behind them.
Also in winter I use the tonneau if I`m(as usual) on my own. I zip open the driver`s side , cover the passenger side with tonneau and put the heater on - it gives quite a bit of warmth at least to one side of the body!
Will use it overnight at the NEC to keep the falling c£$$%p and bird muck off the car - even though parked inside.
