> Can easily pay $15 to essentially go around the corner.

Would it not be better to simply walk if the distance is essentially around the corner?

I love walking - checking distance tracking on my phone, I walked over 20km in a day a couple of weeks ago. But when it's hot in Singapore, the distances I don't want to walk can become crazy-short at times.

I'm hesitating to judge someone taking a ride-share around the corner. Among many other reasons, I can imagine scenarios where someone would think it worth paying to not arrive a sweaty mess.

Rains a lot and often around 30°C. Walking is not always an option if you need to be presentable wherever you're going.

I walk 99% of the time. By around the corner, I mean a 10 - 20 min walk (5 min drive in good traffic), which will easily get you drenched in sweat depending on the weather. If I'm headed to a dinner or gathering that requires a bit of dressing up (shirt and trousers), walking isn't really an option.

Ever tried walking around the corner when it's 35C (95F) and 90% humidity?

It's called a lower bound.
