We need the voice of Optimus Prime.
Thank you for your suggestion. We will add this voice request to our User Request wish-list.

YES!!! I can already imagine Optimus saying "Roll out!" as you begin your drive! We also need to have Megatron's voice that way people can choose if they're team Autobot or team Decepticon ;) I have so many suggestions for how this can go!! It would be a dream come true if this happens
