I gave up on this BRT a loooong time ago, and switched to commuter rail/Grab/Gojek instead. Outside of Thamrin/Sudirman, there's rarely anyone enforcing the issue when non-Transjakarta buses enter the bus lane. On top of that, boarding the buses is usually hellish (never mind rush hour; not to mention, just getting to the bus is often a pain), they're either infrequent or come three at a time (or are too sardine can'd to stop), and I haven't had much luck with the buses being air conditioned. I find them more demoralizing than Kopaja.
OTOH, the commuter rail has improved a fair bit, although boarding begets plenty of scrums, too.
