Front and rear compact seats got upgraded to full size after much complaint. Wheel flop issue from 35 deg pivot angle (positive trail) is also fixed by changing to 60 deg (negative trail). Fly wood board is yet to be added for cargo, animals or 2 small passengers. Flintstones-style push start seems to be a reasonable contribution from rear passenger. We'll test going uphill soon... http://www.youtube.com/watch?v=Y3UY3QUOENQ Vi
