Changes

Take a bus from the center (25/25-P will work) to the base of the ''Pančevački most'' (the bridge over Dunav/Danube -- not any of the ones over the Sava). Take another bus (e.g. 101, 102, 103...) over the bridge, and get off at the first stop after the bridge. Turn around and walk to the elevated motorway back in the direction the bus came (< 100 m). This is the E-70. Coming from the bus stop, the direction East is on the far side of the motorway, so you need to walk under it and then climb up to the level of the highway. Walk right along it (there is a guardrail, so it's not too scary) until you come to a traffic light with a place for buses/cars to pull over immediately afterwards. This is the perfect hitch spot. Continue on the E70 towards Pančevo and Vrsac Vršač and eventually the [[Stamora Moravița-Stamora Vatin border crossing]] into Romania. Be aware that Romanian drivers may expect money, so if a car with a Romanian number plate stops, explain that you will not pay.
