im watching the video quite a bit... i have never seen any car... let alone a relatively 'new' car with such brake issues as locking up... even when bald (i had a 89 chevy celebrity with very badly bald tires all around)
the civic is definately approaching the white car too fast... then wants to change lanes...
the angle is incorrect to tell if the e-brake is pulled for sure, or not...
Blinker-->brakes on-->brakes off--> turn--> brakes on-->wheel turned more...(as in slower speed turn) no countersteer.
if the e-brake wasnt used at all... then the weight shift could've thrown the car out of control... i cant tell if there is a passenger.
...the silver civic could've continued on w/out being hit, and allowed an escape route for the biker.
my best guess is that the driver had a purposeful act... but may have been unaware that your friend was there, rather then a car... the whole brake on/brake off/brake on thing is shady.
Transam...
most of my friends with manual tranny's (and myself when i have owned them) put the parking brake on, and put the car in gear... 1rst if the car is facing uphill, and reverse if facing downhill. this to me is common practice.
and on hills, i will agree... we dont use the e-brake/parking brake at all... we will either feather the clutch/gas, or use the std. foot brake until its clear to go... it all depends on the severity of the hill i think.
the hand-brake is almost never used for actual stopping... i did however use it on my saab quite extensively in empty parking lots...
