You want to have some slack in the wire length for chassis flex and normal movement, but not an extra large amount of wire that has to be curled up, especially if its just one wire and the rest are short. Having wires that are not similar in length creates an unbalanced load of resistance on the phases.
2. As mentioned in my earlier post, the 10 gauge wire is hard to solder properly and has no advantage over 12 gauge. Pictured is an example of how your soldering points need to be on both esc and motor with 12 gauge. A poor soldering job, can cause permanent damage to a unit..
multistrand wire actually passes more current and voltage for RC cars. 1/24 slotcar road course racers and drag racers (even when no movement is needed) use it for the same reason. more strands the better, the more surface area you gain over a solid conductor the same gauge

there is another law that many do not take into consideration, sure ESC designers do, but there is a point were the gauge wire used becomes too large for the available power source resulting in conductivity losses. called called MHO's law also referred to Siemens. i once saw a racer wire up a car with speaker monster wire.
the next big thing RC cars still hasn't occured, is the use on "litz" wire for stators or armatures of years passed. not sure they ever will, in other hobbies it is permanently banned.
litz wire is multistrand arm/stator wire...from wiki
"The wire is designed to reduce the skin effect and proximity effect losses in conductors used at frequencies up to about 1 MHz.[1] It consists of many thin wire strands, individually insulated and twisted or woven together, following one of several carefully prescribed patterns[2] often involving several levels (groups of twisted wires are twisted together, etc.). This winding pattern equalizes the proportion of the overall length over which each strand is at the outside of the conductor. "
