What is going to be the target passenger? People going to the airport? Coming from the airport? Let's look at these 2 first.
Travellers will have baggage. Doesn't look like much room for bags on Lili. "Oh, we are aiming at business travellers, just taking a briefcase for a meeting." Straight away the potential list of passengers is slashed, particularly in Oz, where the customer Lilies into Sydney, gets a taxi to the Quaintas terminal, but then waits for 2 hours, flies to Melbourne for 1.5 hrs, taxi into town, wait, go to the meeting, wait, taxi back to airport, wait 2 hours, fly for 1.5 hrs, go back to Lily Pad - long day.
And then, where does Lili take you (within 30 mins)? It won't be to the street outside your house. It won't be to the sports field 1km from home, the council won't allow that, and then you need another taxi to get home. It won't be to the rooftop terminal for your suburb, it doesn't (and won't) exist.
Dreamers. Take your money, spend some of it on great CGI, pocket the rest.
