maybe also put a sticker on the inside of back seat passenger area so passengers inside your car during your ride can read it from their side window or on the backside head rest of your drivers seat.

by being on the windscreen facing out. its probably more a a conversation of "whats that sticker on your window say" as the conversation starter, because while riding in your car its not so clear what it says from the back seat

other things:
know the times, dates and locations of local bitcoin meetings, events in your area. and be positioned nearby when those events are meant to finish so you can be pinged as the closest vehicle available to give bitcoiners a ride after their event. then seeing they can pay you in bitcoin. they are more likely to get paid in bitcoin

just riding around randomly. is pot luck of finding some random person that wants a ride, also being a bitcoiner.
so increase the chances. by being near known bitcoin events at the time period of the end of the session of a bitcoin event to get paid

and then the rest of the day/week month. the sticker is there to be a conversation starter for those that dont know about bitcoin. where you can also tell them about bitcoin events in your area if they want to learn more/get involved

As sweet savory your story might be to my taste and before my eyes, I don't see how that would work so well in this regard.
A leasta no stranger to both, using the bolt services and bitcoin as well. They've got some short comings to being very applicable.

In one instance, bolt generally generates speculates how long and how many kilometres a ride might last and use that to speculate the price of the ride which is always visible to the passenger. Now, its know that many times, its always about that and on few occasions, traffic and other diversions can alter the price. Hence, its not something you pay as a go but upon arrival and its usually based on the price generated by the driver.

Given the fact that, bitcoin transactions don't come with immediate confirmation timing and has got fees attached to its processing, how do you mediate between these. Increased fee surely ensures faster transactions and that might just be well over 30-50% of your ride fee.
It just doesn't fill convenient and having to wait on transaction to get broadcasted and at least go through some confirmation.

I see. I was curious how you dealt with transaction fees and small amounts of transactions. By any chance, have you taken a look and considered Lightning Network for dealing with micro or small transactions? Would that be applicable and helps you? Or maybe that is out of option due to some reason.

Anyway, It seems that your kind of activity is truly an example the ways of how to helps increasing cryptocurrency, especially bitcoins, adoption within some countries and communities. If there is an available bitcoin payment option, people whether directly or indirectly would be able to conceive of bitcoin's potency and benefit.

Good to know that there are people now in your area of field/side hustle that are bent on making bitcoin their chief medium of exchange.

Well I am looking at the reason for the delay to why your customers weren’t patronizing you in crypto-currency, it may be due to their cautionary measures probably you are in a country with crypto-currency laws.
Regardless you doing well in your part for bitcoin adoption.

Well, as you mention, these stories are more frecuently often in that region.

Very good, I think that somehow the enthusiasm of the users from that part of the world who login here in the forum is contagious.

El Salvador, taxi drivers even have monitors to see the price and related things, look for those stories, they can guide you in more precise ideas.

This is a cool initiative, mate. In my school days, one day in an economics lecture, we were taught about the characteristics of a good entrepreneur, and I remember vividly that a good entrepreneur is a solution finder. It is true that the redesign of the naira note is affecting the people, and as a result, there is not enough cash for citizens to see and spend. But the idea of accepting Bitcoin would be a solution for your customers who would prefer to pay in Bitcoin, and with your sticker on the windscreen, it will also make your new customers curious, and if they are not yet exposed to Bitcoin, they might want to get themselves involved. So, bro, also get ready to teach 😉🥂, because some people may ask you a lot of questions about Bitcoin and others may want you to completely educate them. I am in a position where some of my customers who are not into Bitcoin get to ask me. One thing that surprises me is that some people still think that Bitcoin is only used by fraudsters, popularly known as "yahoo boys," in some countries. While some of my customers would also ask me if there really is any market for Bitcoin (the main thing is that most people are not really aware of the digital currency, decentralized exchange, and centralized exchange), they don't know a thing about Bitcoin or cryptocurrency.

Even if you don't often get customers paying with Bitcoin, the sticker on your windscreen is a good advertisement for Bitcoin, and as Franky suggested, you should also put another sticker in the passenger area. Given Bitcoin's volatility, I usually convert to fiat currency after accepting Bitcoin payment and only keep my profit in bitcoin, so that even if Bitcoin prices fall, I don't have to worry about it because I've already converted my capital to fiat. You could also consider taking that step unless you only want to hold your bitcoin payment without spending any.

Great job! This is the most unique and effective way of promoting bitcoin throw your business. I have seen many photos and threads about integrating bitcoin into their business, but non of them excite me like yours. I have tried to give you some merit but unfortunately I have none

By roaming around with that sticker on your car many people can see and get curious about bitcoin if they don't know about it and knows a little about it. I hope you will not face any legal issues by doing this.

I want to know how the transaction went, like where the rider or customer paid. Like his/her Bitcoin from a personal wallet or from an exchange, and for OP, are you using some payment processor to process the Bitcoin payments? Or just using a personal wallet or exchange account to receive the Bitcoin payments?
Overall, congratulations, OP! Keep it up.

Congratulations for the good decision you made to accept Bitcoin as a payment in your service, just to spread more information about Bitcoin and how safe and fast it's to humanity. I believe, many bitcoiners will like to enter your tax to encourage you not to quit for the tax work for the few customers you are getting now, because with time it will make you a better person that will make people in your areas to celebrate you for the help you have brought to their community by accepting Bitcoin as a payment. I will advise you to also make the stickers available to give some drivers to past it in their cars so that many passengers will know that you accept Bitcoin as payment in the environment.
