Don't want to rain on your parade, however unless your into serious drifting, it's not worth the effort. Video footage whether digital or tape looks pretty ordinary unless your travelling double the posted limit, past othermoving traffic and driving like your being chased by the coppers. Also bear it in mind, if you are into moments of lunacy and you get sprung by the wollopers, they will be very interested in your time/date video footage, seize same and present it in Court at your trial! Just look at any car chase footage, even Police pursuits, unless there is ballistic driving and major carnage, it looks pretty ordinary. You may have innocent intentions and just want footage of what actually happened split seconds before you crashed and are just being considerate to the Coroner. Back to you!
