A street-level count of cars in Busan, South Korea turns up almost no Teslas, a bad sign for the idea that Tesla is about to take over the world's roads.

• An hour of walking Busan's streets turned up just three Teslas among hundreds of cars.
• Hyundai and Kia dominate, with Genesis, Mercedes, BMW, Porsche and even Chinese BYD showing up more often than Tesla.
• Korea's electric shift is already happening without Tesla — most city buses are electric and the Hyundai Ioniq 5 is the standard taxi.
• The recent Tesla robotaxi event in Austin sold a vision that fits car-dependent American cities, not walkable Asian ones with strong mass transit.
• Tesla's outward-swinging doors also draw safety complaints, sitting at eye level when open.

Outlook: Tesla faces a hard sell in markets where local brands are cheap, good, and already electric.
