Tram expensive. I'd rather make my city pay 10x more on road infrastructure and maintenance and then have to buy a car, gas and insurance myself to be able to move.

Bigger roads just leads to more people driving and more traffic, whereas more people using public transport leaves more space for those who insist on travelling with their living room to move unhindered.

This is very common points that come up on this topic, and they are reasonable really, but let me disagree for the following reasons:

I am way more comfortable in my car

This one is obviously very personal, so agreeing or disagreeing makes no sense. We can agree however that when you drive you have to only focus on the road; some people sure enjoy staring at the asphalt or at the ass of the car in front of them while they drive in traffic. Meanwhile on transport one can read, watch a video or even browse feddit posts while a professional driver is paid to do the annoying repetitive part for you. Also when you get on transit the air is already conditioned, meanwhile when you get in your car you left in the parking lot under the sun you enjoy your ass and hands burning while your face freezes to the ac at the max power trying to cool down your box of plastic that turned into a oven.

it goes exactly where I want it and I have complete control over the accessibility

Yeah, meanwhile the transit company of my city calls me every morning and tells me the exact places I am allowed to go today. I definitely don't take whatever line i need to take to go wherever i need or want to be. Jokes aside, if you have bad/non existent public transport in your area your point is understandable. That is literally what we advocate for though, more public transport where there isn't. Cherry on top, I actually have a car and a licence, I just almost never need to use it, because my city has decent (far from perfect, but) transit.

induced demand.. Wait until everyone does the same thing as you are.
