I made several design changes for safety and practicality:

• Batteries moved lower and forward.
• Reinforced electrical area under the hood and opened up air channels.
• Reshaped fenders for wheel clearance.
• Enlarged front bumper and added vent slots.
  Added rear strut rods and emergency brakes.

With these changes, I hope I've addressed most of the practical and safety concerns of making a solar car out of wood. My thought process now will be about the wood joinery and how to reduce weight as much as possible without sacrificing structural integrity.
