At an uncontrolled intersection, four vehicles arrive simultaneously from all four approaches on equal-priority roads. How is right-of-way legally resolved?

1. Traffic law does not establish an automatic single-vehicle right; drivers must establish mutual agreement (dogovor) through clear visual communication before proceeding cautiously
2. The fastest vehicle enters first
3. All four vehicles may proceed simultaneously
4. The motorcycle automatically has right-of-way over all four-wheeled cars
