ESTA: Do I need to say the entire itinerary of my trip?

I am an Italian citizen and I am planning to visit the USA. UU For a 2-week trip, driving a car from Los Angeles to San Francisco.

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

Assuming I'm more interested in a trip "on the road", which means I'll want to stop somewhere by chance and take a room when I'm tired of driving / visiting.

How can I honestly answer these questions without the risk of my ESTA being revoked?
