You don't need a vice to break the folding lock with a nut splitter. The bike and stand will hold the folding lock and prevent it from spinning as you simply turn the ratcheting wrench. The nut splitter stays on from friction. it costs a few dollars and fits in the pants pocket.

Taking a bike on the train or bus is convenient and possibly thousands of people do it every day in the city that I live in. Each train car allows up to 4 bikes outside of peak times. Folding bikes get on at any time. All bikes are free on local trains. Bikes cost money on long distance trains except for folded bikes. Every train I take I've seen at least 2 bikes onboard and sometimes up to 6 bikes.

Let's take a theoretical example. You live 20 minutes on foot to the train station. Take a 45 minute ride inside. And then another 15 minute walk to the final destination. This is 35 minutes of walking each way for 70 minutes walking for the whole trip. Instead if you take your bike with you onto the train, it would be on average 4 to 5 times faster and only take you 15 minutes with a bike instead of 70 minutes walking.


Alternatively at an old job, it was a 25 minute trip by bus including walking and waiting time, or 35 minutes with traffic jam. Taking the bike the entire way was 30 minutes so I rode the bike whenever the weather was good. Then I stored the folding bike under the work desk.
