I assume they just haven't gotten around to that yet. The site only launched today, and airfare is the most expensive part of most journeys. Estimating the cost for driving is not too hard and probably on their roadmap. I asked them about it on Twitter and I'm waiting for their reply :)

I'm the co-founder. You're quite right we simply haven't had time to doing this yet. For lengthy car segment we will show the car rental price and petrol costs - for shorter legs an estimate of the taxi fare. The airfare has been our focus for the beta because it's the most expensive segment of the journey, and also the part most commonly booked upfront.
