90 minutes per day not each way if the commute is 5 miles per day. That’s walking distance of you’re motivated, but if I lived 2.5 miles from work I think I’d commute on my OneWheel at least when it’s not raining.
I don't know how fast they walk down in Australia, but in the USA, that's around 45 minutes each way.
5 miles at 45 minutes is 6.66 miles/hour. Unless most Americans are professional speed walkers I think that's jogging speed.
I think you’re confusing 5 miles / day with 5 miles each way. 5 miles per day is 2.5m each way which is about 45 minutes each way of walking and 90 minutes total walking per day (not each way)
Average walking speed is 3.2 miles/hour or less [1]. That's 94 minutes for 5 miles.
