I don't normally have to drive at night, unless going to Dinner with friends', or to the Theatre. I don't 'avoid' it per se, as there're times you've got to drive at night ie sick relative or one of the kids' may need me.
As for my 'safety', I just take common-sense precautions ie windows' up, doors locked, & mobile at the ready, same as I do during the 'day drives', actually.
