New Killstreak Idea: Exploding Car Thingy

So my idea is after you get a certain killstreak you get the exploding car thing. When you get to the specified killstreak, which I think should be a 10 ks since its not really that powerful, you get a switch that turns you into a silverfish or a chicken and you get speed III or IV and you get a switch. Also maybe you can leave an NPC where you used the car so you can still be killed while in car form. If you get shot while in car form you explode so you need to be careful. Also you wouldn't take fall damage so you won't explode when you fall. When you are near an enemy you use the switch and you explode killing your enemy (or enemies if you're just that awesome) After you use the switch you tp back to where you used the killstreak. Also after about 1 minute you auto-detonate so don't try to get out of the map with dat speed :/ The radius of the explosion will be about 6 blocks and anyone within 1-3 blocks of the explosion dies instantly and anyone outside of that radius gets 5 hearts worth of damage

 

There, made it a bit more specific

 

Man i always come up with ideas after they're taken :/

 

Actually I thought a silverfish might be better since its smaller and has a more car-like shape
but then again, a squirming car would look weird

 

I think this would be OP since you already have speed III. You would be like Matrix dodging all them bullets with your super speed

 

You don't die otherwise nukes would be impossible. You tp back to where you used it with whatever you had before.

 

Yeah pretty much.
