I've spent my whole life without using one

In Pakistan, given the economic situation, people prefer cheaper alternatives for travel, and bikes are a cost-effective option. A bike ride costs me 300 PKR (when booked through an app), while a mini car with AC costs around 1,000 PKR. So, most sensible people might choose to book a bike instead of a car most of the time.

I should renew my membership soon and get back to exercising after the winter!

Try Russian prison exercises instead. They use your own body weight for strength training. Send me a DM, and I can share some books with you. You should definitely read them too!
