What driving in United States is like
California's Highway 1 (Pacific Coast Highway) along the Big Sur coast is among the most iconic American road trips. For most visitors the real draw is the freedom to reach places trains and tours don't, on your own schedule, with the open road generally capped around 55–85 mph depending on state. Getting behind the wheel is the easy part: your International Driving Permit is a certified translation of your Japan licence, carried alongside it, so rental staff and officials in United States can read your credentials at a glance.

Tolling is regional and increasingly cashless/license-plate based; common transponders are E-ZPass (Northeast/Midwest), SunPass (Florida) and FasTrak (California). Rental firms offer toll-pass add-ons (e.g. Enterprise/Hertz) or bill plate-read tolls back with daily admin fees.
Parking in United States

Call 911 for any injury or serious crash. Move vehicles out of traffic only if safe, exchange insurance and licence details, photograph the scene, and file a police report (required in most states above a damage threshold); notify the rental company promptly.

Petrol ('gas') is sold by the US gallon (3.78 L) as Regular 87, Mid 89 and Premium 91-93 octane, plus diesel; stations are nearly all self-serve. Pay at the pump by card, though some require a US ZIP code, so prepay inside if a foreign card is declined.
