there are a couple of options for moving around the Goa area. the taxis [which i hate everywhere in the world], the indian version of the rickshaw [less expensive and more uncomfortable], a scooter [pretty dangerous] or walking [very dangerous]. in the larger cities like Mumbai uber is an option [no cash needed!]
i'm pretty good on a scooter so i get one from the resort to explore around the area and i go to park at the city center where the streets are lined with hundreds of motorbikes that ALL LOOK THE SAME TO ME. fortunately, i have experience in this area. first i take a picture of the bike with identifying numbers. then i take a picture of the shop in front of which i have parked. in this way i have always been able to successfully navigate back to my bike while i watch other travels wandering aimlessly down a street in despair.
Goa, as i mentioned is a hot spot for westerners seeking a cheap place to live or vacation, so along with that comes the chefs to cater to them. there are really lovely western style restaurants around and so when ready to get off the street and take a break from indian food [which i love] there are many options. 
by western standards, drivers in India would be considered reckless and vehicular deaths are in their vedic tradition considered the karmic cost of the pollution created by cars. weekly, if not daily, there are posts on the local fb page of a wrecked motorbike and a note looking to identify the driver who has been now carted off to a hospital.
