There is only so much one can do about other road users who are completely invisible and unpredictable, but fault aside, my guilt would be lower if:
1. I stopped fully at all stop lines (marked or not) and looked carefully both/all ways at every place requiring a stop
2. I drove at the speed limit or less. Less where conditions (traffic, weather, light conditions) are less than optimal.
3. I put 100% of mental focus into driving. No distractions, no in car conversations, let alone cell phone use, no fidding with dials (radio, AC, etc.) except when one can be certain no unexpected situation can occur.
4. I kept my entire windshield and side windows clean and my headlights clean and well adusted.
