I was looking for something like that about a year ago, and the best thing I could find was GameTree. Source: over 3 years ago

BlaBlaCar might be an option due to no trains. Carpooling from people who are travelling via car anyway with spare seats. I haven’t used it myself but check it out. Source: over 1 year ago

It exists called BlaBlaCar: blablacar.com or on App Store (UK): https://apps.apple.com/gb/app/blablacar-carpooling-and-bus/id341329033. Source: almost 2 years ago

Others mentioned something similar, but I would stake out on blablacar.com for the trips from Koloberzeg or nearby to where you live. Someone will eventually do it and you can have them deliver it for you :). Source: about 2 years ago

Well I have my own car. Here in Germany we have the website blablacar.com I've tried it a few times. Works really well, I'm thinking if its worth it to open up a company such as this here since there are only overprized taxis around, or trains which are also not cheap since corona virus.

(2) option 2: Look up blablacar.com, which could either get you straight to Prague, or do part of the journey where trains are awkward, e.g. Keszthely to Bratislava. Source: almost 3 years ago
