By &quot;excellent&quot; I&#x27;m assuming you mean timely and pervasive. I didn&#x27;t find it very welcoming or clean vs., say, Singapore&#x27;s public transport. Both are well used...so here, I claim that this is not due to quality as much as it is due to the cost&#x2F;convenience of using it.<p>I live in Columbus, OH. It&#x27;s pretty much one of the most poorly dense, large (800K) cities in the US. COTA, the public bus system, I use frequently because I pay for a bus pass in my tuition. Their buses are generally clean, drivers are friendly, and I feel safe for the most part (people in Columbus are pretty friendly). However, given the poor density the service times are <i>terrible</i> if you&#x27;re traveling to somewhere other than along the main street. The city is so large for its population that most stops are far and in between. As a result, ridership isn&#x27;t high at all.<p>I think convenience...and cost have a lot to do with it.
