No they are not. Public transport always needs improving, but getting to close where you need to be is always possible. Cycling after that or using some other sort of transport is possible. Even if you do want to ride your own vehicle to desired location, motorcycles are always better than cars. Even more convenient since you can filter through traffic jams, don’t need parking spaces and spend less fuel.
Public Transport takes twice as long to get anywhere for me (and I live fairly close to both trains and buses), and motorcycles are way more dangerous, and can’t really carry anything except yourself. Cars are a happy medium between the two, which is why people use them.
Motorcycles are “way more dangerous” if you drive them that way. Falling off of bicycle, motorcycle or a scooter at 30km/h is the same, with added benefit of wearing a helmet. If you ride it at 200km/h, then there’s little to increase survivability. There’s a reason why speed limits are in place. Sure they are still riskier than armored boxes in which you sit, but they don’t have to be. Also if you really care about safety you’d switch to trains and busses which are significantly more safe than cars.
Depends where you live. If you live in the countryside in ireland, the public transport is severely lacking. A 20 minute drive requires you to take probably 2 hours of public transport.
Edit: After cycling for about… an hour to the train station, so probably 3 hours total
There are always going to be edge cases where personal vehicles make sense, but no serious proponent of better public transport is ever going to propose an outright ban on private vehicular use.
The fact is the majority of people in the world live in urban areas, where there shouldn’t be the excuse of “oh I live hours away from the nearest station and too few people to justify adding a bus route.”
