Car, bike, scooter, and public transport
Over the summer I tried all of them within the span of a single week. It really makes you appreciate how differently each type of road user sees the world.
By car, you're the king of the road. You're surrounded by metal. Your typical annoyances are cyclists and slow drivers in the fast lane — basically anyone who gets in your way. You deal with tailgating and flashing headlights daily. People are in a rush and don't care about anyone else.
By bike, if you're not on a dedicated cycle path you can't avoid mixing it with cars. That creates a ton of potential problems, especially on narrow stretches where two cars barely fit side by side. You're riding practically in the grass while cars fly past. And all it would take is easing off the gas, being a bit more considerate, a bit more anticipating. Don't force your way past a cyclist — just wait for a better spot. And then there's the whole pedestrian-vs-cyclist dynamic. If you need to hop on a pavement briefly to reach a cycle path, most people won't understand. Parents with prams especially.
On the flip side, some cyclists are genuinely aggressive toward drivers.
On a scooter, the big phenomenon today is electric scooters. They're also the biggest danger — in the hands of an inexperienced rider (full speed, on the pavement) they become unguided missiles (they weigh around 10 kg and can do 25 km/h). I ride on pavements too, because there aren't enough cycle paths and I'm scared of the road. But I'm considerate toward pedestrians, which definitely can't be said for everyone.
On public transport, you constantly encounter drivers and cyclists who just aren't paying attention. They'll happily turn left in front of a tram, walk under a bus, block it when it's trying to pull out of a stop — and the list goes on.
In the end you realize we're all just people. What we make of it is what we get. Consideration and anticipating what's happening around you — those are the important things. And it doesn't matter whether you're driving a car, riding a bike, or about to cross the road.
