In a car max lateral acceleration is typically 0.3g for safety and 0.2g for comfort I think (and usually road design are even more conservatory). I think 0.5g lateral is way to high, especially if you can't look at the outside. People are gonna puke or going crazy from the discomfort. Probably < 0.1 might be a good target, maybe even < 0.05g Maybe the capsule should rotate during turns so that most lateral translation is translated to vertical (like in most trains at nominal speed).
