# Question about automobile

What is coming with a car, going with a car, there is no purpose in the car, but the car can not do without it?

• If you didn't come up with the riddle, would you be able to cite where you found it? – Joe-You-Know Aug 22 '18 at 15:34
• @Joe-You-Know I've found it in kids' magazine. – hahaboki Aug 23 '18 at 12:16

2nd Attempt (Probably wrong but worth a shot)

Sound, specifically the static noises that come with running a car?

What is coming with a car,

Sounds that the engine makes, the alternator, etc.

going with a car,

When a car goes by, it makes the vroom sound.

there is no purpose in the car,

The sounds a car makes (besides the horn) serve no function, but they do sound cool.

but the car can not do without it?

While this answer fits the first three pretty well, the last line, I have a problem believing. Electric cars don't really make noise, do they? And saying a car can't do without noise would be a stretch IMHO, except for the horn, which in that case, would serve a purpose. This is why I like my first answer better.

• This was my guess too. I'd say it is the most reasonable answer given here at least. – Carl Löndahl Aug 23 '18 at 10:36

Since

A car is always seen on a road, but the road does not need the car.

• @hahaboki, Really? Wow, I thought I had it for sure. – Joe-You-Know Aug 22 '18 at 15:14
• And I thought it when I heard it for first time. – hahaboki Aug 22 '18 at 15:15
