DC's when that fails, he uses his trusty Batmobile. But Detective Comics #27 revealed that Batman's first set of wheels was also his worst.
Containing the debut of the iconic Batman character, Detective Comics #27 is considered one of the most valuable comic book issues in the history of the medium, only rivaled by the likes of Action Comics #1 (Superman's debut) and Amazing Fantasy #15 (Spider-Man's debut). Unlike many other heroes, Batman would debut practically fully-formed: his relationship with Commissioner Gordon, his cowl and suit, and his detective skills and martial arts prowess all debuted in this issue. His Batmobile arrived as well, but it was a far cry from the vehicles of the modern era.
Tracking down a gang of killers, Batman runs into the police and Gordon, who attempt to chase Batman. Upon finding a clue in the paper, Batman drives off - in his bright-red sports car, the first Batmobile ever. The red Batmobile seemingly has no gadgets and no functionality apart from being a rather fast car - but it's also bright red.
In America, red cars are pulled over by the police more often than the others. This isn't necessarily because drivers of red cars are more likely to speed, but rather because the color red is particularly eye-catching among a sea of brown, black and silver automobiles. For a character who frequently clashes with the police and is even chased by them on the road, this is an awful first start for the Caped Crusader. Not only is the car red, it completely lacks any bat-motif that would become commonplace in later Batmobiles (fins, a bat-head on the hood, and the now-omnipresent color black wouldn't appear for some time).
Fortunately, Batman would quickly abandon his red car - especially on film, where the Tim Burton Batmobile from his 1989 film would go on to inspire all subsequent Batman vehicles on film. While occasionally showcasing glimpses of color (especially in 1997's Batman and Robin), the red car would be limited to early comics and flashback issues. Batman's first Batmobile drew far too much attention on the road, especially for a man who evades the Gotham Police as often as he works with them.
