If this is true, what is EV replacing?

If my commute is less than 100 miles should I not be using train, light rail, trolley, bus, or similar public transport?

The historical use for me and my family and those who has a car, for generation was "road trips", anything over 100 miles.

Where do you live?

In my current city, taking a 10 mile bus ride would take more than an hour, vs. 10 minutes in a car.

I do not live in New York.

Plenty of people drive a car for short trips and those in rural areas will likely continue to do so. Also, consider company vehicles for workers transporting heavy equipment or delivery vehicles. All within the range of current EVs for a full day. EVs won't fix car traffic issues in cities, but public transit won't cover 100% of cases effectively.

For fun, I just looked up my route tomorrow using public transportation.

I typically leave around 6:30am, drive 45 miles and arrive at work about 7:15am.

Using Google and a host of websites to plan, I could walk a mile to catch a regional bus, ride and arrive there 1 hour after I began. I can then walk to another bus station, ride a local bus to a the main bus station, connect to another bus that drops me off pretty much at my workplace. I'd arrive 2.5 hours after I began this journey. The earliest I can get to work by this route is 9:30am. The regional bus system doesn't run any earlier.

Alternatively, if I take our non-ev, it's the same time, but costs 5x as much as our Model Y. The ICE car cost about the same as the EV.
