"Laziness" is a term we use to describe situations where people are unwilling to put in the amount of work necessary to accomplish something that we could do if we were in their situation. The problem with that is that you really have to understand their situation properly first. If you're not a parent then describing someone who drives instead of taking the bus when they're out with their kids as "lazy" is just a show of ignorance. Even if you are a parent, you still don't really know what their kids are like.
Many people do use public transport, and that's great, but I'd hazard a guess that it's largely because they don't have an alternative option rather than because they think it's the best choice. Wrangling kids on buses is really, really hard work. Plus, if you have more than one, it's usually a lot more expensive than driving.
It's not "lazy" to use the most appropriate form of transport.
Please tone down a bit? They sure may have problem in walking maybe a mile or so to reach their destination. Buses aren't dropping them right in front of home.
Every example you give is just laziness.
Many many people in this world use public transport who are elderly, have kids, do the shopping.
Why can't the elderly walk to the bus? Have their legs fell off?
Perhaps people with certain disabilities might have issues that public transport can't solve, but they are not a large part of the population.
