All the traffic at this point is crossing the border, now that both Romania and Bulgaria are in Schengen, no border checks either, and the cars are going pretty slow and do stop to ask where you're going. Be aware that at the time of my crossing, the bridge was getting renovated, and only one way was open, might be difficult to cross on foot if you wanted to, and might make the waiting times longer. But you can walk up to people and ask to take you!
Pretty good place, can get there very easily with tram from Bucharest City Center, and all of the traffic is south, few shops nearby and can easily get back to town if need be.
Might seem great at first sight - border crossing, alcohol shops for cross-border shopping, plenty of stopping space, but all the traffic is extremely local, only reason I got a ride was because the driver got forced by his SO to turn around and grab me for next town, try to get to nearest town for emergency bus/train in case you'd need it
Tons of spaces for drivers to stop, only one exit so they cannot miss you, downside is that it is close to Warsaw, and not much traffic that goes all the way to Krakow if that is your goal
Got dropped off here as the driver had to go to the town near-by, and the bus stop is on the wrong side of road for Warsaw, better off catching a bus up the road, or trying the McDonald's/Gas Station's parking lots, ended up taking a bus as it was getting dark
Definitely mostly local traffic, but if you don't mind that or get lucky, perfect for that. Sadly, next town over - Sejny - doesn't get that much traffic.
