The same advance-payment logic covers the motorway: it's paid ahead of time, with a vignette, vignette, electronic via edalnice.cz, for example €12.30 (10 days). It's bought online or through an app before setting off; a car without one gets fined as soon as a camera reads the plate. Town and regional roads need no vignette; only motorways do.
Without a car, trains are the backbone of getting around the country, and the state operator doesn't run them alone: on the Prague–Brno–Olomouc line, alongside České dráhy, private operators RegioJet and Leo Express also run services, so departure and price get chosen the way a flight would be, not off a single timetable. Prague–Brno takes 2 h 30–37 min, Prague–Olomouc about 2 h 15, both direct.
The same line runs into another Czechia: Prague is not all of it — the country splits into Bohemia in the west and north and Moravia in the east, where Brno and Olomouc are. The difference shows in the accent, in wine as the local drink instead of beer — southern Moravia is wine country — and in visitor numbers, which in both Moravian cities stay well below Prague's.
Beer here is more industry than folklore: Pilsen produced the first golden pilsner-style lager in 1842, now sold as Pilsner Urquell, and the world copied that style from this one city. Czechia has held the world's highest per-capita beer consumption for decades, and its breweries remain one of the few products the country is recognised for abroad, a serious export line.
