ESTA: Do I need to tell all my trip itinerary?

I’m an Italian citizen and I’m planning to visit the USA for a trip of 2 weeks, driving a car from LA to San Francisco.

Reading the ESTA declaration, I found a part where I need to declare Information of a person to contact in USA, with name, address, city and so on.

Assuming that I’m more interested on an “on the road” trip, which means I’ll want to stop somewhere casually and take a room when I’m tired of driving/visiting.

How can I sincerely answer these questions without the risk of having my ESTA revoked?
