How safe is Uber for transporting your children to school or around Manila? Is it a viable option for busy parents?

My brother does this a lot but the yaya is always with my nephew. So far no problems. It's the pick-up that's tricky, compared to the send-off, since he's not there to see where the driver is exactly. It's actually a global trend! http://ph.theasianparent.com/parents-now-sending-kids-school-uber/
