1 - small tank - 3.5 realistic gallons at about 40 mpg MAYBE..
2 - safety - I've been riding awhile and 99% it's not your mistake that you low side or high side but the idiots or cabbies around you.
3 - new rider with no experience, you will probably kill yourself because you will not be good enough to lane split...

traffic/parking/gas <> insurance (expensive for new riders), purchasing bike, helmet, leathers, wheel locks,etc and most important your safety. You will have a lot of oh shit moments.
