How are they planning to ensure sufficient capacity for that? Uber and Lyft both have a system in place where if the demand for rides exceeds the supply of drivers by too much, they can use surge pricing to get more drivers active and lessen the demand. If they're promising a specific reduced price, they won't do that; and if the demand is going to be very high (which seems likely), they might not have enough drivers to satisfy it.
