So here's what happened today: girl who seemed into me offered and gave me a lift home. But I spent the whole time wondering how to create further attraction or escalate the scenario, while she is driving (whoever is driving for that matter).

My go to strategy is eye contact, but this isn't doable when somebody is driving. Then there's kino... but again its not really possible.

We just spent the whole journey talking which is great for comfort but how would I build attraction in a situation like that?

TL;DR: How can I create attraction when either me or the girl is behind the wheel of a car?
