with stronger roofs and redesigned safety emergency exits. they're also recommending better government oversight of drivers and buses and advanced safety features like forward advanced collision systems. >> they want changes. this was the most deadly. there's been a history of crashes with some of these buses. they also, as i understand it, had a camera mounted inside that bus but we haven't seen that video. >> there is no video, apparently, it wasn't recording at the time of the accident. this is a very popular way to travel, very cheap. you often see people lined up in chinatown, you can't get to boston from new york for 30 bucks. it is a big deal. i'm always wondering why there aren't safetybelts, which is crazy. i want to say that about am track trains, we have them on cars, why not have them on something equally large on a highway. >> this was a horrific accident
