It's not like you can forfeit the bail, skip the trial and then just walk away scot-free. There's now a warrant out for your arrest and an additional charge, and you've torpedoed pretty much any chance of leniency.

If it's a serious enough crime, they will come looking for you, and you will not be offered bail a second time. If it wasn't too serious, they might not come looking for you, but you'll have an active warrant so any traffic stop, background check, etc is going to be a huge problem for you. Arguably a worse punishment than whatever you would have gotten if you just showed up at trial.

Maybe if you're planning to never visit that state again or if you're leaving the country entirely and never want to return it might work out, but generally committing additional crimes after you've already been caught for one crime isn't a good idea.
