I think the op here was pointing out that in some gig jobs, you only get paid whilst doing the task (eg delivering the food) rather than the time they are available to work, such as waiting for a food order. The worker can't do anything else whilst waiting, but still doesn't get paid.
Yes, but the same apply to a non-gig jobs with commuting. I understand perfectly that a gig-worker situation is worse and needs more protection, but commuting time, especially when long enough, cannot be just ignored. In fact in many jurisdictions if you get injured while commuting to work, it's a work accident.
